## What is the purpose of the change *Sometimes doCleanup can take a long time (several minutes) while holding submitLock. This slows down other "submitLock" dependent activities. Execute doCleanup without a lock and within its own timer thread. Ignore exception that may occur inside doCleanup() method.* ## How was the change tested *Add concurrency tests to StormTimer and HdfsBlobStoreImpl. Make a temporary code change to insert a four minute delay in topoIdsToClean() after "cleanable.addAll(Utils.OR(store.storedTopoIds(), EMPTY_STRING_SET));". Verify that doCleanup() works and logs a warning that cleanup is taking too long.* -- This is an automated message from the Apache Git Service.
