Namenode runs of out of memory due to memory leak in ipc Server
---------------------------------------------------------------
Key: HADOOP-6460
URL: https://issues.apache.org/jira/browse/HADOOP-6460
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 0.20.1, 0.21.0, 0.22.0
Reporter: Suresh Srinivas
Assignee: Suresh Srinivas
Priority: Blocker
Fix For: 0.20.2, 0.21.0, 0.22.0
Namenode heap usage grows disproportional to the number objects supports
(files, directories and blocks). Based on heap dump analysis, this is due to
large growth in ByteArrayOutputStream allocated in
o.a.h.ipc.Server.Handler.run().
