Subject [jira] [Commented] (HADOOP-11447) Add a more meaningful toString method to SampleStat and MutableStat
Date Tue, 30 Dec 2014 17:54:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14261302#comment-14261302
] 

Steve Loughran commented on HADOOP-11447:
-----------------------------------------

Are you confident that things like variance & stddev are never going to raise errors -or
should that string construction be caught & downgraded to a super.toString()? There's
nothing worse than logging triggering strack traces

> SampleStat and MutableStat don't override the toString method. A more meaningful implementation
could help with debugging.
