Tsz Wo (Nicholas), SZE commented on HADOOP-2755:
------------------------------------------------
> I think this problem takes it root from HADOOP-2683. Also explained in
> HADOOP-1298 ...
Since HADOOP-2633, fsck does not use Server.getUserInfo() anymore. So I guess
this issue is related to other problems. I will perform an investigation.
> dfs fsck extremely slow, dfs ls times out

> Key: HADOOP-2755
> URL: https://issues.apache.org/jira/browse/HADOOP-2755
> Project: Hadoop Core
> Issue Type: Bug
> Affects Versions: 0.16.0
> Environment: Jan 28 nightly build
> With patches 2095, 2119, and 2723
> Reporter: Christian Kunz
> Assignee: dhruba borthakur
> Priority: Blocker
> Fix For: 0.16.0
>
>
> I upgraded a Hadoop installation to the Jan 28 nightly build.
> DFS contains 2.4+ M files.
> Upgrade finished but not finalized.
> Before finalizing I wanted to run fsck on the DFS. It hardly progressed after
> 6 hours (not finished yet). With the '-files' option turned on, it lists
> about 300 entries in 10 minutes.
> And when I tried to list a subdirectory with 100,000 files, it repeatedly
> (about 20 attempts) timed out.
> Changing timeout from 1 to 10 minutes did not help.
