-------------------------------------------------
Key: HADOOP-5059
URL: https://issues.apache.org/jira/browse/HADOOP-5059
Project: Hadoop Core
Issue Type: Bug
Components: util
Environment: On nodes with
physical memory 32G
Swap 16G
Primary/Secondary Namenode using 25G of heap or more
Reporter: Koji Noguchi
We've seen primary/secondary namenodes fail when calling whoami or
topologyscripts.
(Discussed as part of HADOOP-4998)
Sample stack traces.
