Subject [jira] Created: (HADOOP-4961) ConcurrentModificationException in lease recovery of empty files.
Date Wed, 31 Dec 2008 03:02:44 GMT
ConcurrentModificationException in lease recovery of empty files.
-----------------------------------------------------------------

                 Key: HADOOP-4961
                 URL: https://issues.apache.org/jira/browse/HADOOP-4961
             Project: Hadoop Core
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.18.0
            Reporter: Konstantin Shvachko
            Assignee: Konstantin Shvachko
            Priority: Blocker
             Fix For: 0.18.3
         Attachments: TestLeaseExpire.java

The problem is that internalReleaseLease() finalizes empty files, which removes these file
path names from the lease. So this modifies the Collection of file names which {{LeaseManager.checkLeases()}}
is iterating on.
