Raghu Angadi updated HADOOP-553:
--------------------------------
Attachment: logging-exceptions.patch
logging-exceptions.patch:
Patch to write exceptions to log file instead of stderr.
I will submit a seperate patch to rotate .out files.
> DataNode and NameNode main() should catch and report exceptions.

> Key: HADOOP-553
> URL: http://issues.apache.org/jira/browse/HADOOP-553
> Project: Hadoop
> Issue Type: Bug
> Components: mapred, dfs
> Affects Versions: 0.6.2
> Reporter: Konstantin Shvachko
> Assigned To: Raghu Angadi
> Attachments: logging-exceptions.patch
>
>
> Right now we do not know what happened during startup failure,
> because there no records in the logs.
> I propose to change main() so that it would catch exceptions and
> log them rather then throwing them into std out.
> May be the same should be done for the JobTracker.
> The TaskTracker.main() catches at least the IOException.
