--------------------------------

             Summary: A bad error message in DFSStripedOutputStream
                 Key: HDFS-12388
                 URL: https://issues.apache.org/jira/browse/HDFS-12388
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Kai Zheng


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.
