> Improve the unit tests relevant to DataNode volume failure testing
> ------------------------------------------------------------------
>
> Key: HDFS-11353
> URL: https://issues.apache.org/jira/browse/HDFS-11353
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 3.0.0-alpha2
> Reporter: Yiqun Lin
> Assignee: Yiqun Lin
> Attachments: HDFS-11353.001.patch, HDFS-11353.002.patch,
> HDFS-11353.003.patch, HDFS-11353.004.patch, HDFS-11353.005.patch,
> HDFS-11353.006.patch
>
>
> Currently there are many tests which start with
> {{TestDataNodeVolumeFailure*}} frequently run timedout or failed. I found one
> failure test in recent Jenkins building. The stack info:
> {code}
> org.apache.hadoop.hdfs.server.datanode.TestDataNodeVolumeFailureReporting.testSuccessiveVolumeFailures
> java.util.concurrent.TimeoutException: Timed out waiting for DN to die
> at
> org.apache.hadoop.hdfs.DFSTestUtil.waitForDatanodeDeath(DFSTestUtil.java:702)
> at
> org.apache.hadoop.hdfs.server.datanode.TestDataNodeVolumeFailureReporting.testSuccessiveVolumeFailures(TestDataNodeVolumeFailureReporting.java:208)
> {code}
> The related codes:
> {code}
> /*
> * Now fail the 2nd volume on the 3rd datanode. All its volumes
> * are now failed and so it should report two volume failures
> * and that it's no longer up. Only wait for two replicas since
> * we'll never get a third.
> */
> DataNodeTestUtils.injectDataDirFailure(dn3Vol2);
> Path file3 = new Path("/test3");
> DFSTestUtil.createFile(fs, file3, 1024, (short)3, 1L);
> DFSTestUtil.waitReplication(fs, file3, (short)2);
> // The DN should consider itself dead
> DFSTestUtil.waitForDatanodeDeath(dns.get(2));
> {code}
> Here the code waits for the datanode failed all the volume and then become
> dead. But it timed out. We would be better to compare that if all the volumes
> are failed then wair for the datanode dead.
> In addition, we can use the method {{checkDiskErrorSync}} to do the disk
> error check instead of creaing files. In this JIRA, I would like to extract
> this logic and defined that in {{DataNodeTestUtils}}. And then we can reuse
> this method for datanode volme failure testing in the future.
