> Project: Hadoop Core
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.21.0
> Reporter: Hong Tang
> Assignee: Hong Tang
> Priority: Minor
> Fix For: 0.21.0

> Attachments: HADOOP-5149.trunk.patch

>
> When running history viewer in local mode (specifying
> file:///<path/to/hodlogs> as path to logs), it throws
> IndexOutOfBoundsException due to the following code:
> {code}
> String[] jobDetails =
> JobInfo.decodeJobHistoryFileName(jobFiles[0].getName()).split("_");
> trackerHostName = jobDetails[0];
> trackerStartTime = jobDetails[1];
> {code}
> The reason is because there are some directories under the log directories
> that do not conform to the log file naming convention, and the length of the
> jobDetails array is 1.
> History viewer should be more defensive and ignore (possibly with warning)
> files or directories that it does not recognize.
