Description

Reliably seeing failure of this test on an early Hadoop 2.4.0

00:08:07 runTest (simple.merge.MergeTest) ................................... ERROR:test.auto:This looks like a stack trace: Thread "org.apache.accumulo.server.test.functional.FunctionalTest" died split inconsistency foo6_3 [m, b, r] != [r]

The actual failure message is variant across different failure runs (foo6_3 [m, b, r] != [r], foo8_0 [m, b, r] != [m, b], foo7_0 [m, b, r] != [b], etc), but it has failed for me at least 5 times in a row.
