In previous versions of Neo4j (2.X), LOAD CSV would take absolute path from
LOAD CSV WITH HEADERS FROM
'file:///absolute/path/GraphExample2.csv' AS line
However in 3.x, its appending it with NEO4J_HOME to that path.
How does one address absolute path for file imports?
In your configuration file (see here for the documented locations), comment out the dbms.directories.import setting. That will allow neo4j to use your path, as is.
However, commenting out that setting is not secure, so do not do this on production servers.
NOTE: On my Mac, I have the desktop version of neo4j installed. The official documentation seems to have the wrong name for the config file. Mine is named .neo4j.conf, not neo4j.conf.

Just added apoc to a neo4j installation. As a result, got access to the namespaces apoc.coll and apoc.load only. Can't even do basic stuff like RETURN apoc.version().
The jar in the plugins directory contains much more than that, but in the localhost browser, I can't see anything but the above. Both apoc and neo4j version 3.3.
Before editing the config file, apoc was totally unavailable. Additions to config:
dbms.security.procedures.whitelist=apoc.coll.*,apoc.load.*
dbms.security.procedures.unrestricted=apoc.coll.*,apoc.load.*
dbms.security.procedures.whitelist=apoc.algo.*,apoc.atomic.*
dbms.security.procedures.unrestricted=apoc.algo.*,apoc.atomic.*
dbms.security.procedures.whitelist=apoc.trigger.*,apoc.meta.*
dbms.security.procedures.unrestricted=apoc.trigger.*,apoc.meta.*
dbms.security.procedures.whitelist=apoc.*
dbms.security.procedures.unrestricted=apoc.*
apoc.trigger.enabled=true
apoc.ttl.enabled=true
apoc.ttl.schedule=5
apoc.import.file.use_neo4j_config=true
apoc.import.file.enabled=true
apoc.export.file.enabled=true
# apoc.jdbc.<key>.uri=jdbc-url-with-credentials
# apoc.es.<key>.uri=es-url-with-credentials
# apoc.mongodb.<key>.uri=mongodb-url-with-credentials
# apoc.couchbase.<key>.uri=couchbase-url-with-credentials
apoc.jobs.scheduled.num_threads=number-of-threads
apoc.jobs.default.num_threads=number-of-threads
I added 'algo' and 'atomic' as an experiment, as I was thinking that I could see 'load' and 'coll' simply because they were declared in the config. But no - didn't help.
Restarted neo4j and rebooted the machine repeatedly.
I have recently installed Neo4j 3.0, and since I need to enable outside access, I need the configuration file, and where in the 2.3.3 the configuration files were located in within the /var/lib/neo4j/ structure.
I am not able to locate them anywhere in the 3.0 version. I know it have changed name to neo4j.conf.
My folder structure in the above directory is:
plugins
import
data
certificates
I am running Ubuntu 16.04 (Xenial Xerus).
I have tried the documentation. However, that doesn't describe the location. I also already tried "find -name "neo4j.conf" without luck.
[UPDATED]
According to the 3.0.0 Operations Manual, the default location of the config file for "Debian" is:
/etc/neo4j/neo4j.conf
I have Apache OpenMeetings installed and functioning properly.
I am not able to upload Office files to Whiteboard.
I succeeded to upload PDF files.
I installed JODconverter and updated the configuration to match the path.
I installed the OpenOffice to the machine adjust the "Path" environment variable and updated the configuration with the full path to the OpenOffice document.
but still not luck.
am i missing anything?
From openmeetings administration panel, update the office.path configuration too. In this configuration, enter the path of your OpenOffice installation. This should fix the issue.
I created a database Neo4j on a PC, with many relationships, node, etc

thanks for the help

update1: I have tried to found conf/neo4j-server.properties but i don't have...
this is a screenshot of my folder ne04j (It is in Windows document Folder)

Neo4J databases live in your filesystem, you can simply make a copy of the folder in which your Neo4J data is stored. If you are running standalone this folder will be configured in conf/neo4j-server.properties and the line will look something like this:
org.neo4j.server.database.location=data/graph.db
Copy the content of that folder to the graph database folder on your other machine. I'd recommend that your databases are not running when you do this.
I believe you're looking for the dump shell command which you can use to export a database into a single Cypher create statement, you'd "dump" the database and then import it on your new machine.
Information on using the command is outlined here: Neo4j docs
A Neo4j database can be dumped and loaded using the following commands:
neo4j-admin dump --database=<database> --to=<destination-path>
neo4j-admin load --from=<archive-path> --database=<database> [--force]
Limitations
The database should be shutdown before running the dump and load commands.
https://neo4j.com/docs/operations-manual/current/tools/dump-load/
i used the above solution, but the file name was different.
in the folder of the neo4j data, look for folder called conf and inside the configuration file called neo4j.conf
inside this file you will see a line that direct to the folder that contain the data.
its called "graph.db"
replace it with the same folder from your backup of the DB that you want to clone.
Im trying to import csv files from disk with cypher commands as shown in the tutorial, but Im getting "Couldn't load the external resourse at: externalResourceFailure.
Is there any "roadmap" for importing csv in windows from files?
Thank you in advance!
take alook at SyntaxException with Neo4j LOAD command
in the question, step 3, please check if you path to the file is correct on your operating system:
the syntax for accessing a local file on windows is simply "file:c:/nosql/test/unclaimed.csv" and not file:// as might be inferred from examples on ...
You have to put the files into the import directory in neo4j.
it will work if path like this "file:///C:/myfile.csv"
The Windows and Linux file systems require different file URI schemes for streaming over HTTP. Neo4j's LOAD CSV Cypher clause makes an HTTP web request to the URI of a file and not the file system path.
For more information on file URI schemes on Windows please take a look at: http://en.wikipedia.org/wiki/File_URI_scheme#Windows_2
You can also create a folder import into your neo4j installation folder and run a cipher like this
LOAD CSV WITH HEADERS FROM "file:///yourcsvfile.csv" AS row
On mac: create a folder inside the Neo4j directory. Neo4j will install in Documents (by default)
mkdir /Users//Documents/Neo4j/default.graphdb/import
Copy your file in this location
Use it like this
USING PERIODIC COMMIT LOAD CSV WITH HEADERS FROM "file:///user_list.csv" as row create (:Users {userId: row.USER_ID });
