--------------------------------
Summary: Skip unit test using
DataNodeTestUtils#injectDataDirFailure() on Windows
Key: HDFS-8309
URL: https://issues.apache.org/jira/browse/HDFS-8309
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: 2.7.0
Reporter: Xiaoyu Yao
Assignee: Xiaoyu Yao
Priority: Minor
As [~cnauroth] noted in HDFS-7917 below,
DataNodeTestUtils.injectDataDirFailure() won't work for Windows as rename will
fail due to open handles on data node dir. This ticket is opened to skip these
tests for Windows.
bq.Unfortunately, I just remembered that the rename isn't going to work on
Windows. It typically doesn't allow you to rename a directory where there are
open file handles anywhere in the sub-tree. We'd have to shutdown the DataNode
before doing the rename and then start it up. By doing that, we'd be changing
the meaning of the test from covering an online failure to covering a failure
at DataNode startup, so I don't think we can make that change.
Below are the two test cases that need to be fixed:
# TestDataNodeVolumeFailure#testFailedVolumeBeingRemovedFromDataNode
# TestDataNodeHotSwapVolumes.testDirectlyReloadAfterCheckDiskError
