Subject [jira] Commented: (HADOOP-3894) DFSClient chould log errors better, and provide better diagnostics
Date Thu, 15 Jan 2009 02:09:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12663981#action_12663981

Konstantin Shvachko commented on HADOOP-3894:
---------------------------------------------

Steve, I didn't know you worked on this problem 6 months ago. Would have saved me time...
I see there is still an unresolved issue with timeouts in TestMiniMRMapRedDebugScript. We
usually don't appreciate sleeps in unit tests.
So I propose that you 
- isolate the TestMiniMRMapRedDebugScript issue into a separate jira if it is still current.
- incorporate my changes to TestFileAppend3
- and I'll commit the result so that we could close both issues.

Let me know if the plan works for you and how soon it can be done.

> In my test runs I see a stack trace from DFSClient, because it isn't logging through
the log APIs in its close() method. It should use the logger, for better error reporting
