Subject [jira] [Commented] (HBASE-12130) HBASE-11980 calls hflush and hsync doing near double the syncing work
Date Wed, 01 Oct 2014 18:28:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14155253#comment-14155253

stack commented on HBASE-12130:
-------------------------------

[~anoop.hbase] No sir. We are moving off the old calls and on to what is in Syncable (output.sync
does a hflush internally).  Thanks for review.

> The HBASE-11980 change has us doing hflush and hsync every time we call sync (noticed
profiling).  Fix.  Let me expose as config calling one or the other.
