[jira] [Created] (HDFS-15058)
TestFsck.testFsckListCorruptFilesBlocks and
TestFsck.testFsckListCorruptSnapshotFiles fail some times
liusheng created HDFS-15058:
-------------------------------
Summary: TestFsck.testFsckListCorruptFilesBlocks and TestFsck.testFsckListCorruptSnapshotFiles fail some times
Key: HDFS-15058
URL: https://issues.apache.org/jira/browse/HDFS-15058
Project: Hadoop HDFS
Issue Type: Bug
Reporter: liusheng
when I am try to run the tests of HDFS, the *TestFsck.testFsckListCorruptFilesBlocks* and *TestFsck.testFsckListCorruptSnapshotFiles* tests are easy to fail, see:
{code:java}
06:26:38 [ERROR] Failures:
06:26:38 [ERROR] TestFsck.testFsckListCorruptFilesBlocks:1167
06:26:38 [ERROR] TestFsck.testFsckListCorruptSnapshotFiles:2167
06:26:38 [INFO]
06:26:38 [ERROR] Tests run: 33, Failures: 2, Errors: 0, Skipped: 0
{code}
Both of these two tests failures are mainly because the tests will check the number of corrupt files after sleep *1000 ms* and the number is not equal to expected. see:
{noformat}

blk_1073741825 /corruptData/.snapshot/mySnapShot/8117051706407353421
The filesystem under path '/corruptData' has 2 CORRUPT files2. bad fsck include snapshot out: The list of corrupt files under path '/corruptData' are:

To fix these two tests, we need to enlarge the sleep time of 1000 ms, according to my testing, enlaging the time to 5000 ms can ensure tests passed every times.
