[jira] [Reopened] (HBASE-21464) Splitting blocked with meta NSRE
during split transaction
[ https://issues.apache.org/jira/browse/HBASE-21464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Purtell reopened HBASE-21464:
------------------------------------
I reverted my commit because I was able to reproduce the problem again.
That part of the change we removed where the cache lookup for meta region was modified was what was necessary. There is something wrong with the cache lookup. I don't see a change between 1.4.2 and 1.4.3 that is any kind of smoking gun so am a bit stumped here.
