> Key: HDFS-9781
> URL: https://issues.apache.org/jira/browse/HDFS-9781
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 3.0.0-alpha1
> Environment: Jenkins
> Reporter: Wei-Chiu Chuang

> FsDatasetImpl#getBlockReports occasionally throws NPE. The NPE caused
> TestFsDatasetImpl#testRemoveVolumeBeingWritten to time out, because the test
> waits for the call to FsDatasetImpl#getBlockReports to complete without
> exceptions.
> Additionally, the test should be updated to identify an expected exception,
> using {{GenericTestUtils.assertExceptionContains()}}
> {noformat}
