Vinod Kumar Vavilapalli commented on HDFS-6227:
-----------------------------------------------
bq. Checked the test log and had some offline discussion with Vinod Kumar
Vavilapalli. Looks like the issue is that in Yarn some container got killed
while reading a local file through short circuit read. The corresponding file
channel thus got interrupted. Future readers for the same file will then hit
this ClosedChannelException when they fetch the file channel from short circuit
cache.
More specifically, the issue is that a YARN container got killed during
localization and so the resource-localization process got interrupted, thereby
interrupting the DFS client read also.
