Subject [jira] [Commented] (HADOOP-9422) HADOOP_HOME should not be required to be set to be able to launch commands using hadoop.util.Shell
Date Wed, 05 Jun 2013 19:51:21 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13676278#comment-13676278

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.

> Not sure why this is an enforced requirement especially in cases where a deployment is
done using multiple tar-balls ( one each for common/hdfs/mapreduce/yarn ).
