    Description

      I saw this failure once on my internal Hudson job that runs the append tests 48 times a day:
      junit.framework.AssertionFailedError: expected:<114688> but was:<98304>
      at org.apache.hadoop.hdfs.AppendTestUtil.check(AppendTestUtil.java:112)
      at org.apache.hadoop.hdfs.TestFileAppend3.testTC2(TestFileAppend3.java:116)
