Hi Team,
We are continuously getting *"PermGen space" *error. We have increased
Mapper and its Heap size also. but no luck. we are using hive 1.2.
When i search in google, it has been said that preserved memory has
exceeded. our cluster is 4 nodes, each 4 cpu core and 7 GB RAM. File or
internal table is in MB only.
Is there a way to increase *-XX: PermSize, *What settings should i keep
to resolve this error
*
*Exception in thread "main" java.lang.OutOfMemoryError: PermGen space
