Description

DAGAppMaster's memory gradually keeps increasing when running simple tez apps repeatedly in session mode. Taking memory snapshots revealed that FileSystem.CACHE is getting populated with some keys which are not being released.

Around 200KB of data is leaked for every job invocation in the session mode. I will attach the profiler snapshots soon. Haven't figured out yet on who makes the call to FileSystem.get() and not calling close().
