Description

TestHLogSplit.testTralingGarbageCorruptionFileSkipErrorsPasses fails against a version of hadoop with https://issues.apache.org/jira/browse/HADOOP-8230

The failure:
"java.io.IOException: Append is not supported. Please see the dfs.support.append configuration parameter."

Instead of using append, we can probably just:

• copy over the contents to a new file
• append the garbage to the new file
• copy back to the old file
