> I've been running tests before commit and found the following happens with some regularity, sporadic of course, but they fail fairly frequently:
> {code}
> Failed tests:   testOnlineChangeTableSchema(org.apache.hadoop.hbase.client.TestAdmin)
>   testForceSplit(org.apache.hadoop.hbase.client.TestAdmin): expected:<2> but was:<1>
>   testForceSplitMultiFamily(org.apache.hadoop.hbase.client.TestAdmin): expected:<2> but was:<1>
> {code}
> Looking, it seems like we fail to find .tableinfo in the tests that modify table schema while table is online.
> The update of a table schema just does an overwrite.  In the tests we sometimes fail to find the newly written file or we get EOFE reading it.
