Subject [jira] [Commented] (HBASE-6134) Speed up distribued split log
Date Wed, 30 May 2012 06:59:23 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13285442#comment-13285442

Zhihong Yu commented on HBASE-6134:

So your suggestion is to estimate log splitting duration based on number of HLog files ?
If the estimate is low, we stay with master log splitting.

> First,we do the test between local-master-split and distributed split log
> Environment:34 hlog files, 5 regionservers,(after kill one, only 4 rs do ths splitting
> local-master-split:60s+
> distributed-split-log:165s+
> In fact, in our production environment, distributed-split-log also took 60s with 30 regionservers
for 34 hlog files (regionserver may be in high load)
> We found split-worker split one log file took about 20s.
> I think we should do the improvement for this.
