Subject [jira] [Commented] (MAPREDUCE-6704) Container fail to launch for mapred application

bq.   But since its a mapreduce property its not correct to add to the whitelist of yarn .

Why can't MR add it itself?

bq. But since its a mapreduce property its not correct to add to the whitelist of yarn .

Who cares?  It's all Apache Hadoop. Users have an expectation that this stuff will work *out
of the box* and be *consistent*.  They aren't going to say "Oh, of course this is completely
broken!  That part over there is YARN and that part over there is MAPREDUCE!"

bq. IIUU HADOOP_MAPRED_HOME for default installation will be same as HADOOP_COMMON_HOME .

It's irrelevant.  HADOOP_MAPRED_HOME is where the mapred stuff is guaranteed to be.   There
is no guarantee that HADOOP_COMMON_HOME is going to work. That's why there is a separate variable
for it instead of just using HADOOP_COMMON_HOME everywhere.  Either this should be HADOOP_MAPRED_HOME
or set nothing at all.

> As part for launch script {{HADOOP_MAPRED_HOME}} default value is not set .After https://github.com/apache/hadoop/commit/9d4d30243b0fc9630da51a2c17b543ef671d035c
  {{HADOOP_MAPRED_HOME}} is not able to get from {{builder.environment()}} since {{DefaultContainerExecutor#buildCommandExecutor}}
sets inherit to false.
