> when I am try to run the tests of HDFS, the *TestFsck.testFsckListCorruptFilesBlocks* and *TestFsck.testFsckListCorruptSnapshotFiles* tests are easy to fail, see:

> 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:

> 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 make the tests passed every times.
