Description

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 "org.apache.hadoop.dfs.SecondaryNameNode@73eb904d" java.lang.OutOfMemoryError: GC overhead limit
