Abraham Elmahrek commented on SQOOP-1397:
-----------------------------------------
[~hshreedharan], sorry... I didn't catch the convig/env variable thing. That's
exactly what we would try to achieve. There would need to be a flag that turns
on and off debugging in Sqoop2 server.
> Sqoop2: Attach a debugger to miniclusters/ MR tasks at launch
> -------------------------------------------------------------
>
> Key: SQOOP-1397
> URL: https://issues.apache.org/jira/browse/SQOOP-1397
> Project: Sqoop
> Issue Type: Improvement
> Affects Versions: 2.0.0
> Reporter: Abraham Elmahrek
> Assignee: Veena Basavaraj
>
> It would be nice to have a way to attach a debugger to the miniclusters:
> http://cargo.codehaus.org/Starting+and+stopping+a+container and
> http://cargo.codehaus.org/Configuration+properties.
> For tomcat, I needed to add the following to TomcatSqoopMiniCluster:
> {code}
> configuration.setProperty(GeneralPropertySet.JVMARGS,
> "\"-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005\"");
> {code}
> There should also be a way to attach a debugger to the Yarn container.
