Renaming of table throws out of memory exception.

[Anandha L Ranganathan <an...@gmail.com>]

I am trying to rename a table but it throws OOMException.

One way to resolve is to  increase the memory ,  but I would like to
understand how renaming of table  throws OOMException.


hive> ALTER TABLE <<TABLE_NAME>> RENAME TO <<TABLE_NAME_OLD>>;

java.lang.OutOfMemoryError: GC overhead limit exceeded
