batch-processing - JanusGraph 可以在 Windows 10 上运行吗

Question

我正在 Windows 10 上运行 janusgraph-0.2.0-hadoop2 .

我已将 winutils.exe 放入 bin 文件夹中。

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

我快速浏览了 bat 脚本并添加了一些 echo 语句:

    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"

输出:

这个问题也在 janusgraph-users 上被问过。 Google 网上论坛，我已将我的答案复制到此处:

JanusGraph does run on Windows 10. The user experience is not ideal, and could use some help with people with Windows expertise. I've opened up issue 950 to track making the prepackaged distribution more Windows-friendly.

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.

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.
