Subject [jira] [Commented] (HADOOP-9487) Deprecation warnings in Configuration should go to their own log or otherwise be suppressible
Date Tue, 04 Jun 2013 17:11:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13674568#comment-13674568

Sangjin Lee commented on HADOOP-9487:
-------------------------------------

[~stayhf] I'm not sure which part of my comment you're referring to... When we run any mapreduce
job that uses old properties, the log is flooded with the deprecation warnings to the point
that it is often hard to make out other legit warnings or errors. I support the idea that
provides an ability to suppress these deprecation warning messages if a certain boolean option
is enabled.

> Running local pig jobs triggers large quantities of warnings about deprecated properties
-something I don't care about as I'm not in a position to fix without delving into Pig. 
> I can suppress them by changing the log level, but that can hide other warnings that
may actually matter.
> If there was a special Configuration.deprecated log for all deprecation messages, this
log could be suppressed by people who don't want noisy logs
