> When running TestDFSStripedOutputStreamWithFailure testCloseWithExceptionsInStreamer we often get OOM errors. It's not every time, but it occurs frequently. We have reproduced this on a few different machines. This seems to have been introduced in f83716b7f2e5b63e4c2302c374982755233d4dd6 by HDFS-13251.
