Subject [jira] [Created] (HADOOP-8382) Failure in deleting user directories in Secure hadoop
Date Thu, 10 May 2012 01:42:48 GMT
Benoy Antony created HADOOP-8382:

             Summary: Failure in deleting user directories in Secure hadoop
                 Key: HADOOP-8382
                 URL: https://issues.apache.org/jira/browse/HADOOP-8382
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: security
    Affects Versions: 0.22.0
            Reporter: Benoy Antony
            Assignee: Benoy Antony
             Fix For: 0.22.1

This happens when security is enabled on 22

When TaskTracker starts p, it invokes MRAsyncDiskService moves the contents of scratch/tasktracker
to toBeDeleted under a directory created with the current timestamp.
The owner of this directory is hadoop (owner of tasktracker)

The contents of this directory are various usernames and they are owned by individual users.
But MRAsyncDiskService tries to delete the newly created directory as hadoop and it fails.
