Subject [jira] [Created] (HDFS-5127) TestDataNodeVolumeFailureReporting and TestDataNodeVolumeFailureToleration timeout on ZFS

Adam Pocock created HDFS-5127:
---------------------------------

             Summary: TestDataNodeVolumeFailureReporting and TestDataNodeVolumeFailureToleration
timeout on ZFS
                 Key: HDFS-5127
                 URL: https://issues.apache.org/jira/browse/HDFS-5127
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
    Affects Versions: 2.0.3-alpha, 2.0.0-alpha
         Environment: Solaris 11.1, x86-64
            Reporter: Adam Pocock
            Priority: Minor


TestDataNodeVolumeFailureReporting and TestDataNodeVolumeFailureToleration timeout on ZFS,
due to an inaccurate method of measuring node capacity. Filesystems like ZFS which store additional
metadata do not return absolutely consistent capacities after filesystem changes, so the logic
which controls these two tests (in DFSTestUtil.waitForDatanodeStatus) fails as (expectedCapacity
!= currTotalCapacity), and the tests timeout. This occurs even when the ZFS filesystem and
pool live on a ramdisk. The tests pass correctly when using a UFS filesystem on a ramdisk,
and so the problem is ZFS rather than Solaris specific.
