Regions not assigned after HBASE-2694 went in
---------------------------------------------
Key: HBASE-2757
URL: https://issues.apache.org/jira/browse/HBASE-2757
Project: HBase
Issue Type: Bug
Reporter: stack
Priority: Blocker
Fix For: 0.21.0
Looking into the Hudson failure,
http://hudson.zones.apache.org/hudson/view/HBase/job/HBase-TRUNK/1339/ at the
failing
org.apache.hadoop.hbase.client.TestFromClientSide.testRegionCachePreWarm test,
I seem to be seeing a case of regions being added to UNASSIGNED up in zk but
then subsequently nothing. Adjacent regions are being similarily added but
these are being assigned out. Somethings up. It seems to be causing the above
test failure.
Its hard to see in the logs....
Grep for this line:
LOG.info("Starting testRegionCachePreWarm");
The unit test then does TEST_UTIL.createMultiRegions.
You'll see all regions being created and then they UNASSIGNED znodes are
created. Grep for the 'eee' row from testCachePrewarm table (be careful, there
is also logging for testCachePrewarm2 in this log).
The last thing you'll see is:
2010-06-19 19:34:39,628 DEBUG [RegionManager.metaScanner]
master.RegionManager(1006): Created UNASSIGNED zNode
testCachePrewarm,eee,1276976076048.557068905bf2abfe84a5e49953a23c02. in state
M2ZK_REGION_OFFLINE
For ddd and fff, you'll see those assigned out.
Maybe the test is not hanging about long enough but wonder why its skipped?
