I am using Datastax enterprise edition and in cluster one is Hadoop/Hive .I am trying to connect to hive with datastax hive odbc connector.I am getting error like :
Connector Version: V1.0.0.1007
Running connectivity tests...
Attempting connection
Failed to establish connection
SQLSTATE: HY000[DataStax][Hardy] (22) Error from ThriftHiveClient: connect() failed: errno = 10061
TESTS COMPLETED WITH ERROR
The error 10061 means connection refused
Seems like you have not started the hive service on your Analytics node therefore nothing is listening on TCP 10000
Please login into one of your DSE Analytics node and execute:
dse hive --service hiveserver
Then try again your test from your Windows system

I created a testchannel and tried to join peer to it using the codes below.
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin#org1.example.com/msp
export CORE_PEER_ADDRESS=peer1.org1.example.com:7051
peer channel join -b testchannel.block
But connection error occured as below.
Error: error getting endorser client for channel: endorser client failed to connect to peer1.org1.example.com:7051: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp 172.18.0.3:7051: connect: connection refused"
I tried the solutions mentioned in other similar posts such as changing the CORE_PEER_TLS_ENABLED but it still occured. How to solve it? Thanks!
You will need to check the docker log of the peer
docker logs <container id>

Reason for error: CentOS 6.5 system kernel version is 2.6.32, which is less than 3.9. However, SO_REUSEPORT only supports Linux 3.9 and above.
Upgrading the system to CentOS 7.5 can solve the problem by itself.
I am trying to start Neo4J embedded db (3.2.0) and then access this db from another jvm process via bolt driver (1.4.4). Although my code below do print sysouts indicating that db has started,
System.out.println("Starting Neo embedded database at " + databaseFile);
BoltConnector bolt = new BoltConnector("key");
service = new GraphDatabaseFactory().newEmbeddedDatabaseBuilder(new File(databaseFile))
.setConfig(bolt.enabled, "true").setConfig(bolt.type, "BOLT")
.setConfig(bolt.encryption_level, "DISABLED").newGraphDatabase();
System.out.println("Started Neo embedded database");
my another jvm process running on same machine trying to query db via bolt driver fails with below error:
Exception in thread "main" org.neo4j.driver.v1.exceptions.ServiceUnavailableException: Unable to connect to localhost:7687, ensure the database is running and that there is a working network connection to it.

I have been using flume for a while now, I have got agent and collector running on same machine.
Configuration
agent: exec("/usr/bin/tail -n +0 -F /path/to/file") | agentE2ESink("hostname", 35855)
collector: collectorSource(35855) | collector(10000) { collectorSink("/hdfs/path/to/sink","name") }
Facing issues in the agent node:
2012-06-04 19:13:33,625 [naive file wal consumer-27] INFO debug.InsistentOpenDecorator: open attempt 0 failed, backoff (1000ms): Failed to open thrift event sink to hostname:35855 : java.net.ConnectException: Connection refused

I dont understand why the connection is refused. Are there any system level changes that needs to be done ?
Note: the collector is listening to the port but agent is unable to send data through the 35855 port.
Can anyone help me with this problem.
Thanks
If you are running both the agent and the collector on the same box, you should be using localhost as the address.
agentE2ESink("localhost", 35855)
