Setting Java options on the DagAM

Hi all,

I'd like to set some JVM flags for the DagAM (specifically remote
debugging in this case) but I don't see any way of doing that. IIRC,
this used to be possible. Any pointers?

Thanks,
Mark

There is TezConfiguration.TEZ_AM_JAVA_OPTS in code which corresponds to
adding "tez.am. java.opts" on the client tez-site.xml

Hi Mark,

Code snippet from TezClient#createApplicationSubmissionContext():

    vargs.add(amConfig.getAMConf().get(TezConfiguration.TEZ_AM_JAVA_OPTS,
        TezConfiguration.DEFAULT_TEZ_AM_JAVA_OPTS));

It uses the TezConfiguration from AMConfiguration to extract the java opts for the AM. For log level, you will need to set TezConfiguration.TEZ_AM_LOG_LEVEL. 

Filed TEZ-557 for the missing docs.  

thanks
