Todd Lipcon commented on HDFS-3770:
-----------------------------------
I don't think the interruption is related -- I think we have some kind of
subtle race on the DN side with the "recomputing last chunk" when appending to
a partial chunk - basically the same issue as HDFS-1057 but specific to right
as the file is reopened for append.

> TestFileConcurrentReader#testUnfinishedBlockCRCErrorTransferToAppend failed
> on [a recent job|https://builds.apache.org/job/PreCommit-HDFS-Build/2959].
> Looks like a race in the test. The failure is due to a ChecksumException but
> that's likely due to the DFSOutputstream getting interrupted on close.
> Looking at the relevant code, waitForAckedSeqno is getting an
> InterruptedException waiting on dataQueue, looks like there are uses of
> interrupt where we're not first notifying dataQueue, or waiting for the
> notifications to be delivered.
