> The recoverLease test in this class sets hbase.lease.recovery.pause to 10ms. It causes that after every 10 ms, it calls isFileClosed (if it is available). Though the test takes only 3-4 sec, but it makes about 270 isFileClosed calls. This cause test to become somewhat flaky in our internal testing.
> The proposed fix is to just to increase the pause interval to 100 ms. This reduces the number of calls to about 30.
