Jay Finger commented on HADOOP-8433:
------------------------------------
I don't like the approach of commenting this line out. I think a lot of admins
will infer from this that uncommenting the line will result in some useful
behavior.
A bigger problem is that hadoop-env.sh is sometimes included twice. For
example, hadoop-daemon.sh includes hadoop-config.sh, which includes
hadoop-env.sh. Then later hadoop-daemon.sh includes hadoop-env.sh explicitly.
It seems to me that this is the actual root cause of the issue, and that it is
likely going to cause other headaches in the future by people who don't suspect
that it will be included twice.

> It's better to comment the following in hadoop-env.sh
> # Where log files are stored. $HADOOP_HOME/logs by default.
> export HADOOP_LOG_DIR=${HADOOP_LOG_DIR}/$USER
> Because of this logs are placing under root($user) and this getting called
> two times while starting process.
> hence logs are placing at /root/root/
