Subject [jira] [Commented] (HBASE-15506) FSDataOutputStream.write() allocates new byte buffer on each operation
Date Wed, 30 Mar 2016 15:16:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15218113#comment-15218113

stack commented on HBASE-15506:
-------------------------------

bq. In any case, we should be able to create some single server test workload that exhibits
problems if there are any. 

Thanks for the refresher [~lhofhansl] Agree would like to see evidence of benefit; in this
case, we'd get new configs, a mechanism we'd be first to use (I think), and in testing in
the past, no discernible benefit.
