Kihwal Lee commented on HDFS-9574:
----------------------------------
This precommit (#13934) and #13935 for HDFS-7163 ran on H9 at the same time,
causing both to run for over 5 hours and failing many tests due to internal
timeout.
[~aw], do you think we can configure jenkins to avoid this? Since HDFS tests
are run in parallel, concurrent hdfs builds are worse than before.
