Re: Setting Java options on the DagAM

[Hitesh Shah]

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
