Ted Yu updated HBASE-17427:
---------------------------
Description:
Intermittently, region_mover.rb got stuck waiting for region to be moved onto
same server:
{code}
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
{code}
This was due to the following:
{code}
# Make a fake servername by appending ','
metaServer = (mtl.getMetaRegionLocation(zkw).toString() + ",").to_s
{code}
Note the extra comma appended to server name (as can be seen in above log)

{code}
This was due to the following:
{code}
if currentServer and servername and currentServer == servername.to_s
{code}
currentServer is Java String which shouldn't be compared with ruby string
directly.
