Subject [jira] [Created] (HDFS-4283) Spurious Test failures in TestEditLog.testFuzzSequences
Date Thu, 06 Dec 2012 07:01:01 GMT
Colin Patrick McCabe created HDFS-4283:
------------------------------------------

             Summary: Spurious Test failures in TestEditLog.testFuzzSequences
                 Key: HDFS-4283
                 URL: https://issues.apache.org/jira/browse/HDFS-4283
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
    Affects Versions: 2.0.3-alpha
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
            Priority: Minor


testFuzzSequences fails sometimes due to the additional UTF-8 validation added in HADOOP-9103.
 The issue is that the UTF8 class throws its exceptions as {{RuntimeExceptions}} rather than
{{IOExceptions}}, and the fuzzing code is not expecting that.

Example failure:
