Phabricator updated HBASE-4704:
-------------------------------
Attachment: D117.1.patch
mbautin requested code review of "HBASE-4704 [jira] A JRuby script for
identifying active master".
Reviewers: Kannan, Liyin, JIRA
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 adding a one-line hbase-jruby script
so we can make our jruby scripts proper UNIX executables by including an
"#!/usr/bin/env hbase-jruby" line at the top.
TEST PLAN
Run it. Kill the master. Wait for znode to expire. Run again.
