Description

TestAdmin.testCreateBadTables failed on me once with the following exception:

2013-11-25 13:37:27,832 ERROR [0] server.NIOServerCnxnFactory$1(44): Thread Thread[0,5,main] died
java.lang.RuntimeException: Failed threaded create0

Caused by: org.apache.hadoop.hbase.client.RegionOfflineException: Only 2 of 1 regions are online; retries exhausted.

	at org.apache.hadoop.hbase.client.TestAdmin$3.run(TestAdmin.java:1065)

It seems one region is split while we are still expect the region count to be 1.
