Description
I would like to pull back some fixes for the DataNodeVolume* tests to resolve some intermittent failures we are seeing on branch-2.10.
The fixes are:
HDFS-11353 Improve the unit tests relevant to DataNode volume failure testing
HDFS-13993 TestDataNodeVolumeFailure#testTolerateVolumeFailuresAfterAddingMoreVolumes is flaky
HDFS-14324 Fix TestDataNodeVolumeFailure
HDFS-13945 TestDataNodeVolumeFailure is Flaky
