Subject [jira] [Commented] (YARN-448) Remove unnecessary hflush from log aggregation
Date Mon, 04 Mar 2013 16:17:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13592321#comment-13592321

Robert Joseph Evans commented on YARN-448:

Yes I don't see any real reason to have that hflush there. If log aggregation crashed either
before or after that point it really would not make that much of a difference. +1, assuming
Jenkins comes back with a +1.

> AggregatedLogFormat#writeVersion() calls hflush() after writing the version. Calling
hflush does not seem to be necessary. It can add a lot of load to hdfs in a big busy cluster.
