hbase-1506 where assignment is done at regionserver doesn't work
----------------------------------------------------------------
Key: HBASE-1890
URL: https://issues.apache.org/jira/browse/HBASE-1890
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
Fix For: 0.20.1, 0.21.0
I have been running testing of 0.20.1 and found a bunch of cases where
regionserver adding the bottom half to .META. itself is causing double
assignment; we add the regioninfo over on the regionserver and then queue up
the opening of the region. Meantime along comes BaseScanner and it finds the
two new regions, one of which its in charge of assigning but one of which its
not to assign -- but it does because the server and startcode are empty.
Here is example:
