Kafka stream window aggregation almost working - docker
I need to aggregate some sensor data and I'm experimenting with windowed aggregation for a PoC/study project.
After researching here and there and a lot of attempts, I came up with the following code, which seems to be working.
I get in fact the peeks showing the expected results and I can also see the deserialisation/serialisation of the SensorData object happening through the stream.
And I can see the final result in the output topic.
Here is the problem though: after the first result is written in the output topic, the stream crashes and it crashes earlier or later depending on the length of the commitMs.
Any idea? Am I doing something wrong here?
I am using a landoop/fast-data-dev docker image to test this.
long commitMs = TBD;
Properties config = new Properties();
config.put(StreamsConfig.APPLICATION_ID_CONFIG, "sensor-data-stream-analyzer");
config.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, "kafka-cluster1:9092");
config.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest");
config.put(StreamsConfig.DEFAULT_KEY_SERDE_CLASS_CONFIG, Serdes.String().getClass());
config.put(StreamsConfig.DEFAULT_VALUE_SERDE_CLASS_CONFIG, Serdes.String().getClass());
config.put(StreamsConfig.COMMIT_INTERVAL_MS_CONFIG, commitMs);
config.put(StreamsConfig.DEFAULT_TIMESTAMP_EXTRACTOR_CLASS_CONFIG, WallclockTimestampExtractor.class);
final Serializer<SensorReport> jsonSerializer = new MyJsonSerializer();
final Deserializer<SensorReport> jsonDeserializer = new MyJsonDeserializer(SensorReport.class);
final Serde<SensorReport> jsonSerde = Serdes.serdeFrom(jsonSerializer, jsonDeserializer);
final Serde<String> stringSerde = Serdes.String();
final Serde<Long> longSerde = Serdes.Long();
StreamsBuilder builder = new StreamsBuilder();
KStream<String, SensorReport> stream =
builder.stream(inputTopic, Consumed.with(stringSerde, jsonSerde));
stream
.peek((k,v)-> System.out.println("1|k: " + k + "v: " + v.toString()))
.map((key, sensorReport) -> {
double[] fakeLatLon = new double[]{10,10};
return KeyValue.pair(String.format("%f %f", fakeLatLon[0], fakeLatLon[1]), sensorReport);
})
.peek((k,v)-> System.out.println("2|k: " + k + "v: " + v.toString()))
.groupByKey(Serialized.with(stringSerde, jsonSerde))
.windowedBy(TimeWindows.of(10000L).until(10000L))

.toStream((k, v) -> String.format("%d %s", k.window().start(), k.key()))
.peek((k,v)-> System.out.println("3|k: " + k + "v: " + v.toString()))
.map((k,v) -> KeyValue.pair(k, v.toString()))
.to(outputTopic, Produced.with(stringSerde, stringSerde));
KafkaStreams run = new KafkaStreams(builder.build(), getConfig());
run.start();
And this is the relevant part of the stack trace:

OS:NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.9.2
PRETTY_NAME="Alpine Linux v3.9"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://bugs.alpinelinux.org/"
I solved my problem and I'm going to share my solution here for whoever ends up having this same problem.
Initially the stack trace line "C [librocksdbjni6827723631295059350.so+0x3e13b5] rocksdb::ParseColumnFamilyOption(std::string const&, std::string const&, rocksdb::ColumnFamilyOptions*, bool)+0xc95" led me to think it was a musl-libc vs glibc related issue as mentioned in the following two issue links:
https://github.com/facebook/rocksdb/issues/3848
https://github.com/facebook/rocksdb/pull/3143
In fact I use a landoop/fast-data-dev:latest docker image, which is Alpine based. But a quick look at the landoop/fast-data-dev, shows that the author dealt with the glibc:
https://github.com/Landoop/fast-data-dev/blob/master/Dockerfile
# glibc : alpine linux has an embedded libc which misses some functions that are
# needed by some apps (e.g jvm's rocksdb jni — HDFS connector, Lenses, etc),
# so we add glibc to make them work. Also now we can add en_US.UTF-8 locale.
# https://github.com/sgerrand/alpine-pkg-glibc
The crash went away by simply replacing the kafka-stream dependency in my pom.xml from
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-streams</artifactId>
<version>2.0.1</version>
</dependency>
to
<dependency>

<artifactId>kafka-streams</artifactId>
<version>2.2.0</version>

ESP8266 BearSSL MQTT Exception when connecting
I am trying to connect to HiveMQ MQTT Broker from my ESP8266, 2 months ago, this code works fine, but now, when I implement more features, the code run with a lot of Exceptions. Sometimes, Exception (28), I'm newbie in this fields and don't know the way to handle it, thanks for your helps.

PSclient->setServer(MQTT_ADDRESS.c_str(), MQTT_PORT);
PSclient->setBufferSize(512);
PSclient->setCallback(myCallback);
}
void loop()
{
wifiConfig.configWifiAP(ENV_SSID_AP, ENV_PASS_AP);
if (!PSclient->connected())
{
reconnect();
}
else

I expect to a successful and stable connection to MQTT Broker
Mtdoops cannot save the full panic log
I add a mtd partition (512kb) to save panic log by mtdoops on an arm based embedded devices(kernel v4.4). I trigger the panic using "echo c > /proc/sysrq-trigger". After the device reboot observe the kernel panic logs in the Oops partition by "strings", but the panic log seems to be truncated(limit in 2kb?). How to change the limit of mtdoops? # strings /dev/mtd22 ]<4>[ 99.089308] r3 : 00000001 r2 : 00000000 r1 : ef717364 r0 : 00000063 <4>[ 99.095905] Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user <4>[ 99.102416] Control: 10c5787d Table: 6652c06a DAC: 00000055 <0>[ 99.109618] Process ash (pid: 234, stack limit = 0xee672210) <0>[ 99.115350] Stack: (0xee673ec8 to 0xee674000) <0>[ 99.121077] 3ec0: 00000002 ee80b200 00000001 00000000 c0301d24 c058a8dc <0>[ 99.125336] 3ee0: c058a8a0 c0421b98 00000002 c0421b28 ee673f88 b675fbf0 c0301d24 c03df2ec <0>[ 99.133495] 3f00: 00000000 000006c0 00000000 00000000 00000000 ee673f18 be461b48 0000000b <0>[ 99.141656] 3f20: eeab0218 0000000a eeab0240 00080000 ee673f60 ee7531f8 00000001 e4b70780 <0>[ 99.149816] 3f40: ef046998 c0355734 00000002 00000002 e4b70780 ee673f88 b675fbf0 c03df9c0 <0>[ 99.157975] 3f60: e4b70780 b675fbf0 00000002 e4b70780 e4b70780 b675fbf0 00000002 c0301d24 <0>[ 99.166134] 3f80: ee672000 c03e009c 00000000 00000000 00000002 00000000 00000000 00000000 <0>[ 99.174294] 3fa0: 00000004 c0301b80 00000000 00000000 00000001 b675fbf0 00000002 00000000 <0>[ 99.182455] 3fc0: 00000000 00000000 00000000 00000004 00000002 be4619cc 00000020 7f087b44 <0>[ 99.190615] 3fe0: be461958 be461944 b67b66ac b67b5b78 60000010 00000001 00000000 00000000 <4>[ 99.198784] [<c058a480>] (sysrq_handle_crash) from [<c058a7dc>] (__handle_sysrq+0x88/0x124) <4>[ 99.206940] [<c058a7dc>] (__handle_sysrq) from [<c058a8dc>] (write_sysrq_trigger+0x3c/0x4c) <4>[ 99.215102] [<c058a8dc>] (write_sysrq_trigger) from [<c0421b98>] (proc_reg_write+0x70/0x84) <4>[ 99.223435] [<c0421b98>] (proc_reg_write) from [<c03df2ec>] (__vfs_write+0x1c/0xd0) <4>[ 99.231763] [<c03df2ec>] (__vfs_write) from [<c03df9c0>] (vfs_write+0xa8/0x130) <4>[ 99.239401] [<c03df9c0>] (vfs_write) from [<c03e009c>] (SyS_write+0x40/0x80) <4>[ 99.246695] [<c03e009c>] (SyS_write) from [<c0301b80>] (ret_fast_syscall+0x0/0x34) <0>[ 99.253986] Code: e3a03001 e5823000 f57ff04e e3a02000 (e5c23000) <4>[ 99.268628] UBI# UBI# UBI# # # # strings /dev/mtd22 | wc -c 2057 # #
*** stack smashing detected ***: a.out terminated
So I'm working on a program in my Programming I class and we were assigned to create a program that will check to see if a routing number from a bank is valid. Every time I run this program on NetBeans, I have no issue. BUT, when I run it through our Ubuntu student server, I get this crazy error. I've been trying to debug this program for a while now and can't quite see where this error is originating from. I've tried changing the array sizes and with no luck, I'm still getting this error. Here is a copy of the error:
Enter a bank routing number:
103000648
1 0 3 0 0 0 6 4 8
7 3 9 7 3 9 7 3
7 0 27 0 0 0 42 12
7 7 34 34 34 34 76 88
88
8
the check code is valid

you try to build with gcc option -fsanitize-address, it will crash at the point where you are writing beyond stack.
OpenCV: free(): invalid next size error when resizing matrix
I need to acquire some points' coordinates (represented by variables xCoord and yCoord) and set to 1 the associated positions in matrix scan_image. It may happen that a point's coordinates are outside matrix's dimensions, so scan_image needs to be resized before setting point's associated position in matrix to 1.
Here's the code:

I tried many options to modify scan_info's dimensions (you'll find them in comments) in case denoted as CASE 3, but everytime I get a bad memory error:

Conflict with ruby and nginx on my production server?
I have a weird problem on my production server. There are Ubuntu server, nginx + phusion passenger installed on it. I manage my ruby version with rvm and it's ruby 1.9.3-p327 and rails 3.2.9. Sometimes, it's impossible to deploy my app because the rake asset:precompile task failed. When I try to execute this directly on my server I have the same problem. Same trace when I run bundle exec rails c production Here a part (the end) of the trace (I'm sorry, I don't have the complete trace because it's too long): 3.2.0/lib/paperclip.rb 966

Bug reports are welcome. For details: http://www.ruby-lang.org/bugreport.html What is interesting is the end of the trace, which said there is a bug in the ruby interpreter. One time I have the beginning of the trace and It said something like this: *** glibc detected *** ruby: double free or corruption (!prev) For the moment to fix the bug I need to restart nginx. It's for this reason I ask this question: Is it a conflict between ruby and nginx or inside ruby interpreter? And how to solve this? Thanks Edit : Error already appear. I wonder if it's not a problem due to ImageMagick. Indeed a cron task execute some times by a day an upload of pictures. When there are not lot of pictures everything seems to be fine. But when there is about 100 pictures every two hours I have the feeling that the error appear. I will inspect this way. If somebody have an idea...
Try, export MALLOC_CHECK_=2. Because of this glibc will do extra level of checking during free(), to avoid heap corruption. It will abort() and give a core dump as soon as it detects corruption, instead of waiting until there's an actual problem caused by the corruption. or use http://valgrind.org/ for more details.
