NPE in RackResolve

Key: YARN-1032
URL: https://issues.apache.org/jira/browse/YARN-1032
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 2.0.5-alpha
Environment: linux
Reporter: Lohit Vijayarenu
Assignee: Lohit Vijayarenu
Priority: Critical
Attachments: YARN-1032.1.patch, YARN-1032.2.patch
We found a case where our rack resolve script was not returning rack due to
problem with resolving host address. This exception was see in
RackResolver.java as NPE, ultimately caught in RMContainerAllocator.
