-------------------------------------
Summary: Memory leak in tez session mode
Key: TEZ-1585
URL: https://issues.apache.org/jira/browse/TEZ-1585
Project: Apache Tez
Issue Type: Bug
Reporter: Rajesh Balamohan
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().
