If you unzip titan-1.0.0-hadoop1.zip on Windows, you'll see errors out of the box.

C:\titan-1.0.0-hadoop1>bin\gremlin.bat
Error opening zip file or JAR manifest missing : ..\lib\jamm-0.3.0.jar
Error occurred during initialization of VM
agent library failed to init: instrument

C:\titan-1.0.0-hadoop1\bin>gremlin.bat
The input line is too long.
The syntax of the command is incorrect.

I think the fix is to get the gremlin*.bat files better aligned with the latest from TinkerPop3. There are some additional Titan-specific changes required for the jamm-0.3.0.jar and the slf4j/logback conflict.

For the gremlin-server

C:\titan-1.0.0-hadoop1>bin\gremlin-server.bat

This is looking in the wrong location by default. In the titan zip, the file is located at conf/gremlin-server/gremlin-server.yaml.

So this actually starts, but the logging here is incredibly noisy because the logback binding is getting loaded on the classpath before the slf4j binding. It seems that the preferred way in Titan is to put slf4j before logback, but Effy offered another workaround to put a logback.xml in $TITAN_HOME:

<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>
  <root level="info">
    <appender-ref ref="STDOUT" />
  </root>
</configuration>

I will have a pull request coming for this. Testing is still in progress, but you can look find it at https://github.com/pluradj/titan/tree/titan11-windows-bat

Hi - this resolved the gremlin.bat "The input line is too long." issue for me. Thanks,

[spmallette]

@pluradj do you still have a PR coming for this?

[technotrance]

This is solely my own repository

[pluradj]

@spmallette yeah, finally dusted off the Win machine again for TP3 voting. I'll get the PR submitted based off the branch linked above.

[spmallette]

cool - i'd really like to get a titan release put together soon. the delay has been good in some sense, but there have been a lot of bug fixes on the TP side that titan should support at this point

[sheymann]

Any news about a fix?
