[jira] Updated: (HADOOP-6609) Deadlock in
DFSClient#getBlockLocations even with the security disabled
[ https://issues.apache.org/jira/browse/HADOOP-6609?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Konstantin Boudnik updated HADOOP-6609:
---------------------------------------
Summary: Deadlock in DFSClient#getBlockLocations even with the security disabled (was: Deadlock in DFSClient#getBlockLocations with the security enabled)
This problem happens on vanilla cluster with the security off, However, the executed code belongs to the secured Hadoop. Thus, I'm changing the title of the JIRA.
