Vinod Kumar Vavilapalli commented on HADOOP-12451:
--------------------------------------------------
[~kasha], looked at the original patch for HADOOP-11464, I think there are more
bugs:
- We should also fix the following line?
{code}+HADOOP_OPTS="$HADOOP_OPTS -Dhadoop.home.dir=$HADOOP_HOME"{code}
If it isn't cygwin, it is supposed to point hadoop.home.dir to HADOOP_PREFIX as
it was doing before.
- The same fix (your patch and the change I suggest above) definitely needs to
also happen in hadoop-yarn-project/hadoop-yarn/bin/yarn?
> Setting HADOOP_HOME explicitly should be allowed

> explicitly in hadoop-config.sh without checking if it has already been set.
