Subject [jira] [Commented] (HADOOP-8888) add the ability to suppress the deprecated warnings when using hadoop cli
Date Sat, 06 Oct 2012 18:05:03 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13471078#comment-13471078

Harsh J commented on HADOOP-8888:
---------------------------------

Am not liking this idea, personally.

We ought to fix bad config references not suppress them. For instance, I'd gone through a
few logs of startup to remove unnecessary warnings regarding deprecation and what not for
HDFS recently, same should be done for this - why can't that be carried out?

This toggle will make users find them and get more lazier and then someday bite them. We warn
for a reason?
