      Description

      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:

      Failed
      
      org.apache.hadoop.hdfs.server.namenode.TestEditLog.testFuzzSequences
      Failing for the past 5 builds (Since Failed#3600 )
      Took 4.8 sec.
      Error Message
