Work Description: steveloughran commented on pull request #2361:
URL: https://github.com/apache/hadoop/pull/2361#issuecomment-704335369
tests with markers=keep & delete all good other than
* continuous read() under-fulfillment breaking tests which expect their
buffers to always be full. Root cause clearly some networking issue, but where?
* ITestS3AInputStreamPerformance stream had to be reopened 3 times, rather
than 1. Didn't come back on a rerun.

> an incidental part of HDP-13230 was a fix to innerGetFileStatus, wherein
> after a HEAD request we would update the DDB record, so resetting it's TTL
> Applications which did remote updates of buckets without going through
> s3guard are now triggering failures in applications in the cluster when they
> go to open the file
