Subject [jira] [Commented] (HDFS-3816) Invalidate work percentage default value should be 0.32f instead of 32
Date Mon, 20 Aug 2012 18:29:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13438061#comment-13438061

Aaron T. Myers commented on HDFS-3816:

Good find, Jing.

One suggestion: perhaps in DFSUtil#getInvalidateWorkPctPerIteration we should also check that
the configured value of this config is not greater than 1.0f? If I'm reading the code correctly,
it doesn't make any sense to set this value to anything outside of the range 0.0f-1.0f. Jing,
if you agree with this, mind filing another JIRA? I'd be happy to review it if you post a
patch. If not, I'll take care of it.

Also, Suresh, did you commit this to branch-2.1.0-alpha as well as branch-2? If not, I believe
the fix version should be set to 2.2.0-alpha. Do you agree?
