             Summary: The open sequence number will grow if we fail to open a 
region after writing the max sequence id file
                 Key: HBASE-20242
                 URL: https://issues.apache.org/jira/browse/HBASE-20242
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang


We write the current max sequence id plus one as the new max sequence id so if 
we fail before report RIT to master, when assign next time the open sequence 
number will increase by one.

But it is possible that we fail before writing the open region marker so there 
will no actual WAL with the sequence id which is the open sequence number minus 
one. This will cause the serial replication to be stuck.
