Subject [jira] Updated: (HADOOP-498) fsck should execute faster
Date Tue, 10 Oct 2006 22:51:21 GMT
     [ http://issues.apache.org/jira/browse/HADOOP-498?page=all ]

Milind Bhandarkar updated HADOOP-498:

    Attachment: fsck.patch

Attached patch. fsck functionality is moved into namenode aand made available as a servlet.
This avoids multiple roundtrips from dfs client to the namenode. The commandline interface
for fsck on the client now uses http to do fsck. Also added a test for fsck. Also, fixed the
copyFiles test to actually run instead of exiting.

> on a good size dfs, with a few 100000 blocks, fsck takes around 30 minutes, while dfs
-du takes only a couple of seconds.
> fsck should take seconds, rather than minutes. It should be a namenode operation, not
a client program.
