Todd Lipcon commented on HBASE-2757:
------------------------------------
Yea, but I added another clearRegionCache call after the countRows to get it
back to being empty
> Regions not assigned after HBASE-2694 went in

> Looking into the Hudson failure,

> 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?
