Phabricator updated HBASE-4704:
-------------------------------
Attachment: HBASE-4704.D117.2.patch
mbautin updated the revision "HBASE-4704 [jira] A JRuby script for identifying
active master".
Reviewers: Kannan, Liyin, JIRA
Fixing the script to actually work on trunk. Tested on a dev cluster, killed
the master, tested again, got "Master not running" after znode expiration.
Hacked the script to use incorrect ZK port, got a ZK exception and a nonzero
error code, as expected.

> This simple script reads the HBase master ZK node and outputs the hostname of
> the active master. This is needed so that operational scripts can decide
> where the primary master is running. I am also including a one-line
> hbase-jruby script so we can make our jruby scripts proper UNIX executables
> by including an "#!/usr/bin/env hbase-jruby" at the top.
