Subject [jira] [Commented] (HBASE-15206) Flakey testSplitDaughtersNotInMeta test
Date Wed, 03 Feb 2016 07:43:39 GMT

huaxiang sun commented on HBASE-15206:
--------------------------------------

[~eclark] Not sure about the real cluster. With 2.0, it is less likely to happen, it seems
that child region compaction does not happen after split. With branch1.2, child region compaction
happens right after child regions are open when useZKForAssignment is true.

> From the log, the ntp issue caused clock skew and it woke up CatalogJanitor earlier.
The CatalogJanitor cleaned up the parent region. It could happen with master branch as well.
The fix is to disable CatalogJanitor to make sure this will not happen.
