Roman Shaposhnik commented on HADOOP-8010:
------------------------------------------

@Matt, thank a lot for committing it!

@Eli, the difference between hadoop-config.sh and everything else is that hadoop-config.sh doesn't control which scripts are sourcing it (it is meant to be sourced not executed) and thus needs to be as POSIX compliant as possible. The rest of the scripts where '==' is used in Hadoop 1.0 branch are all specifying #!/usr/bin/env bash so there's no issue.
