> Noticed a failure reported by Jenkins in HDFS-11882. The reported error message wasn't
correct, it should be: {{the number of failed blocks = 4 > the number of data blocks =
3}} =>  {{the number of failed blocks = 4 > the number of parity blocks = 3}} 
> {noformat}
> Regression
> org.apache.hadoop.hdfs.TestDFSStripedOutputStreamWithFailure030.testBlockTokenExpired
> Failing for the past 1 build (Since Failed#20973 )
> Took 6.4 sec.
> Error Message
> Failed at i=6294527
> Stacktrace
