Subject [jira] Created: (HADOOP-4351) ArrayIndexOutOfBoundsException during fsck
Date Mon, 06 Oct 2008 14:13:44 GMT
ArrayIndexOutOfBoundsException during fsck
------------------------------------------

                 Key: HADOOP-4351
                 URL: https://issues.apache.org/jira/browse/HADOOP-4351
             Project: Hadoop Core
          Issue Type: Bug
    Affects Versions: 0.18.1
            Reporter: Brian Bockelman


After observing a lot of corrupted blocks, I suddenly started to get a lot of ArrayIndexOutOfBoundsException.

It appears to be an issue very similar to HADOOP-3649, which is supposed to be fixed in 0.18.1.
