Hemanth Yamijala updated HADOOP-3304:
-------------------------------------
Attachment: 3304.1.patch
The attached patch adds documentation as mentioned by Vinod to the HOD admin
guide. Some refactoring is required in writing unit tests, but reserving that
for another patch as we would like to get this into Hadoop 0.17. ASAP.
> [HOD] logcondense fails if DFS has files that are not log files, but match a

>
> logcondense works by listing files in dfs and match them against a certain
> pattern. This pattern is incorrect in the sense that it can potentially match
> files that are not log files. And this can cause it to fail and not delete
> files correctly as it should.
> It should use a correct regular expression that will only list log files.
> Also, possibly it should log a stack trace if it happens, but continue to
> delete files and not stop.
