Subject [jira] [Created] (HBASE-3719) Workload has to drain before hlog can be rolled

Workload has to drain before hlog can be rolled
-----------------------------------------------

                 Key: HBASE-3719
                 URL: https://issues.apache.org/jira/browse/HBASE-3719
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


In the current implementation, the regionserver blocks new transactions from occuring when
the HLog is rolled. Closing the existing HLog sometimes takes more than a few seconds and
during this time all new puts/increments are blocked. It will be nice if we can continue to
write new transactions to the new HLog (but maybe not commit those transactions) while the
old HLog is being closed.
