Subject [jira] [Commented] (MAPREDUCE-5970) Provide a boolean switch to enable MR-AM profiling
Date Mon, 06 Oct 2014 21:05:35 GMT

Jason Lowe commented on MAPREDUCE-5970:
---------------------------------------

Thanks for the patch, Gera!  Looks good overall.  It should be straightforward to add a test
case to TestYARNRunner to verify the new property behaves as expected, see TestYARNRunner.testAMAdminCommandOpts
as an example.

> MR task profiling can be enabled with a simple switch {{mapreduce.task.profile=true}}.
We can analogously have {{yarn.app.mapreduce.am.profile}} for MR-AM
