Robert Joseph Evans commented on MAPREDUCE-2801:
------------------------------------------------
To clarify a little Mahadev's question TaskRunner.java (in 0.23) line 392
calls parseChildJavaOpts.
parseChildJavaOpts is replaced by lines 348 and 349 in YARNRunner.java
{code}
String[] javaOptsSplit = conf.get(MRJobConfig.MR_AM_COMMAND_OPTS,
MRJobConfig.DEFAULT_MR_AM_COMMAND_OPTS).split(" ");
{code}
and also the method getChildJavaOpts and lines 223 and 225 in
MapReduceChildJVM.java
{code}
String javaOpts = getChildJavaOpts(conf, task.isMapTask());
{code}
{code}
String [] javaOptsSplit = javaOpts.split(" ");
{code}
> Include the native libs in java.library.path
