[jira] Commented: (HADOOP-6630) hadoop-config.sh fails to get executed if hadoop wrapper scripts are in path

    [ https://issues.apache.org/jira/browse/HADOOP-6630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12844305#action_12844305 ] 

Allen Wittenauer commented on HADOOP-6630:
------------------------------------------

Since we require bash, we can cheat a bit. BASH_SOURCE should contain the full path to the script that we are executing. This means we can piggyback off of that variable to figure out where our real landing path is at.

> If the hadoop/bin commands are in the path, hadoop-config.sh doesn't executed until much later in the stack because $0 lacks a path.
