Subject [jira] Commented: (HADOOP-1192) Du command takes a noticable longer time to execute on a large dfs than the 0.11 release
Date Mon, 02 Apr 2007 21:30:32 GMT

Raghu Angadi commented on HADOOP-1192:
--------------------------------------

+1 Code looks fine.

While reviewing this I noticed that FsShell.dus() seem to be doing one level recursion into
the paths it wants to du. I would have thought we either need not recurse at all or to recurse
recurse fully. This patch does not change this logic. Hairong is taking a look at this. If
there is some issue here (either correctness or just code efficiency), that could be a different
jira.

> After installing 0.12.2, we notice that the du command takes a much longer time to execute
than the previous release. Another problem is that dus prints a negative value.
