-----------------------------
Summary: [AMv2] If Master gives OPEN to another, if original
eventually succeeds, Master will kill it
Key: HBASE-18103
URL: https://issues.apache.org/jira/browse/HBASE-18103
Project: HBase
Issue Type: Sub-task
Reporter: stack
If a RS is slow to open a Region, the Master will give the Region to another to
open it (In this case, was a massive set of edits to process and a load of
StoreFiles to open...). Should the original RS succeed with its open
eventually, on reporting the master the successful open, the Master currently
kills the RS because the region is supposed to be elsewhere.
This is an easy fix.
The RS does not fully open a Region until Master gives it the go so just close
the region if master rejects the open....
See '6.1.1 If Master gives Region to another to Open, old RS will be kill
itself on reject by Master; easy fix!' in
