Assignee: (was: Dhruba Borthakur)
Resolution: Incomplete
> 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, wal
> Reporter: Dhruba Borthakur
> Priority: Major
>
> 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.
