Subject [jira] [Created] (HBASE-4742) Split dead server's log in parallel
Date Thu, 03 Nov 2011 20:53:32 GMT
Split dead server's log in parallel
-----------------------------------

                 Key: HBASE-4742
                 URL: https://issues.apache.org/jira/browse/HBASE-4742
             Project: HBase
          Issue Type: Improvement
            Reporter: Liyin Tang
            Assignee: Liyin Tang


When one region server goes down, the master will shutdown the region server and split its
log.
However, splitting log is a blocking call and it would take some time.

If more than one region server go down, the master will split its log one by one, which is
not efficient.
Since we have the distributed log split, we could split these logs from the dead servers in
parallel.
