SecondaryNamenode process should exit if it encounters Runtime exceptions
-------------------------------------------------------------------------
Key: HADOOP-2209
URL: https://issues.apache.org/jira/browse/HADOOP-2209
Project: Hadoop
Issue Type: Bug
Components: dfs
Reporter: dhruba borthakur
Fix For: 0.16.0
I saw a case when the SecondaryNamenode encountered a OutOfMemory exception
because the fsimage and edits file were too big to fit into the Secondary
Namenode's memory. However, the process did not exit.
Exception in thread "[EMAIL PROTECTED]" java.lang.OutOfMemoryError: GC overhead
