> While fixing HBASE-2643, I noticed that a couple of the HLogSplit tests from HBASE-2437
were now failing.  3 tests are trying to detect proper handling of garbage data: testCorruptedFileGetsArchivedIfSkipErrors,
testTrailingGarbageCorruptionLogFileSkipErrorsFalseThrows, testCorruptedLogFilesSkipErrorsFalseDoesNotTouchLogs.
 However, these tests are corrupting data at the HBase level.  Data corruption should be tested
at the HDFS level, because the filesystem is responsible for data validation.  These tests
need to inject corrupt data at the HDFS level & then verify that ChecksumExceptions are
thrown.
