Description

Problem

When launching zeppelin-0.9.0 on Windows and execute any paragraph, it will throw exceptions:

The error log is:

zeppelin-kangrong-KANGRONG-PC.log

 

Debugging

We found that zeppelin launches the interpreter at 

org.apache.zeppelin.interpreter.util.ProcessLauncher#launch()

and then calling `bin\interpreter.cmd` (Windows) or `bin\interpreter.sh` (unix).

`interpreter.xx` will call `org.apache.zeppelin.interpreter.remote.RemoteInterpreterServer` to run an interpreter.

However, the input parameters are different between these two scripts:

 

// interpreter.sh provides four paramters:
"${ZEPPELIN_SERVER}" "${CALLBACK_HOST}" "${PORT}" "${INTP_GROUP_ID}" "${INTP_PORT}"

// interpreter.cmd only input the first twos:
%ZEPPELIN_SERVER% "%CALLBACK_HOST%" %PORT%

 

 

As a result, `RemoteInterpreterServer` cannot read args[2] as GroupId and throw `ArrayIndexOutOfBoundsException`.

// org.apache.zeppelin.interpreter.remote.RemoteInterpreterServer#main
public static void main(String[] args) throws Exception {
   ...
  if (args.length > 0) {
    zeppelinServerHost = args[0];
    port = Integer.parseInt(args[1]);
    interpreterGroupId = args[2];
    ...
  }
   ...
}

Solution

I'd like to submit [PR-3995|https://github.com/apache/zeppelin/pull/3995] to fix bugs in `interpreter.cmd`.
