Subject [jira] [Created] (HBASE-17427) region_mover.rb may move region onto the same server
Date Wed, 04 Jan 2017 22:57:58 GMT
Ted Yu created HBASE-17427:

             Summary: region_mover.rb may move region onto the same server
                 Key: HBASE-17427
                 URL: https://issues.apache.org/jira/browse/HBASE-17427
             Project: HBase
          Issue Type: Bug
    Affects Versions: 1.1.6
            Reporter: Ted Yu
            Assignee: Ted Yu

Intermittently, region_mover.rb got stuck waiting for region to be moved onto same server:
2017-01-04 05:37:27,830|INFO|MainThread|machine.py:145 - run()|RuntimeError: Region hbase:meta,,1.1588230740
stuck on ctr-e88-1483482546062-0245-01-000007.x.com,16020,1483507665481,, newserver=ctr-e88-1483482546062-0245-01-000007.x.com,16020,1483507665481
This was due to the following:
    if currentServer and servername and currentServer == servername.to_s
currentServer is Java String which shouldn't be compared with ruby string directly.
