Arpit Gupta commented on HADOOP-9422:
-------------------------------------
I can take this up.
One thing we could do is not have the static variable defined but call the
appropriate method when needed. I will upload a patch for that. Also it looks
like getHadoopHome is not being used in the project and getQualifiedBinPath is
being used in getWinUtilsPath only when windows env is there.
So we would also remove getHadoopHome and leave the getQualifiedBinPath there.
> HADOOP_HOME should not be required to be set to be able to launch commands
> using hadoop.util.Shell
