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.
