Subject [jira] Created: (HADOOP-194) Distributed checkup of the file system consistency.
Date Thu, 04 May 2006 02:12:18 GMT
Distributed checkup of the file system consistency.
---------------------------------------------------

         Key: HADOOP-194
         URL: http://issues.apache.org/jira/browse/HADOOP-194
     Project: Hadoop
        Type: Test

    Reporter: Konstantin Shvachko


This is a map-reduce based test that checks consistency of the file system
by  reading all blocks of all files, and detecting which of them are missing or corrupted.
See HADOOP-95 and HADOOP-101 for related discussions.

This could be an alternative to the sequential checkup in dfsck.
It would be nice to integrate distributed checkup with dfsck, but I don't yet see how.

This test reuses classes defined in HADOOP-193.
