> Initiator class determines compaction type periodically. Initiator either
> runs as hive user or impersonates the owner of the table. When impersonation
> is used, Initiator#checkForCompaction may leak memory. If impersonation
> (ugi.doAs()) call fails, FileSystem.closeAllForUGI does not run, therefore
> does not clean the file system cache.
