Does Janusgraph run on Windows 10?

[Kaliyug Antagonist]

Windows 10, janusgraph-0.2.0-hadoop2.

I have put the winutils.exe in the bin folder.

P:\Software\DB\NoSQL\janusgraph-0.2.0-hadoop2\bin>gremlin-server.bat
Error: Could not find or load main class Files

I had a quick look at the bat script and added some echo statements:

echo "%1"

IF "%1" == "-i" ( 
    GOTO install
) else (
    GOTO server
)

:: Start the Gremlin Server

:server

IF "%1" == "" (
  SET GREMLIN_SERVER_YAML=%JANUSGRAPH_HOME%\conf\gremlin-server\gremlin-server.yaml
) ELSE (
  SET GREMLIN_SERVER_YAML=%1
)

java %JAVA_OPTIONS% %JAVA_ARGS% -cp %CP% org.apache.tinkerpop.gremlin.server.GremlinServer %GREMLIN_SERVER_YAML%

echo %JAVA_OPTIONS%
echo %JAVA_ARGS%
echo %CP%
echo %GREMLIN_SERVER_YAML%
echo "call to GremlinServer"

The output:

JanusGraph does run on Windows 10. The user experience is not ideal, and could use some help with people with Windows expertise.

Your problem is probably coming from your CLASSPATH variable, and I'd think that ".;C:\Program Files (x86)\QuickTime\QTSystem\QTJava.zip;" is messing it up because of the spaces in the path. Try unsetting the CLASSPATH before running gremlin-server.bat.

I had to remove the CLASSPATH variable, it, at least, started. Now I am getting errors pertaining to the CassandraThriftStoreManager but I will post a different question for that(I guess it expects a Cassandra instance up and running)

[Jason Plurad]

Yes, the default Gremlin Server configuration uses janusgraph-cassandra-es-server.properties because the pre-packaged distribution bin/janusgraph.sh start will start a single node Cassandra, a single node Elasticsearch, and the Gremlin Server. If you want to run with Cassandra, you could go a version directly from the Apache Cassandra site or a Datastax distribution if you want to go with an MSI installer. If you're not interested in using Cassandra, you could change the gremlin-server.yaml to use the janusgraph-berkeleyje-server.properties which is pretty good for getting started.

I'm sorry there isn't currently a better answer right now, but the quick start distribution is mostly packaged for Linux, since most contributors have developed on Linux-capable platforms and I'd imagine most applications deploy onto Linux for production.

I've opened up issue 950 to track making the prepackaged distribution more Windows-friendly.
