Subject [jira] [Commented] (HADOOP-7573) hadoop should log configuration reads
Date Tue, 23 Aug 2011 21:29:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13089779#comment-13089779
] 

Aaron T. Myers commented on HADOOP-7573:
----------------------------------------

bq. I changed the fix-version; will that cause the QA system to test against the appropriate
version?

Nope, there's currently no way of doing that. See this JIRA for more details: HADOOP-7435

You should manually run the test-patch.sh script against the correct branch on your machine
and paste the output in a comment on this JIRA.

> For debugging, it would often be valuable to know which configuration options ever got
read out of the Configuration into the rest of the program -- an unread option didn't cause
a problem. This patch logs the first time each option is read.
