[jira] Commented: (HBASE-2467) Concurrent flushers in HLog sync using HDFS-895

    [ https://issues.apache.org/jira/browse/HBASE-2467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12859032#action_12859032 ] 

stack commented on HBASE-2467:
------------------------------

Patch looks good to me (What you think j-d?).  I need hdfs-895 in place to play with this, right?

> HDFS-895 changes hflush() to be able to run concurrently from multiple threads, where flushes can be concurrent with further writes to the same file.
> We need to rip out/amend the group commit code a bit to take advantage of this.
