> testSplitRegionIsDeleted failed in Hadoop-Nightly #207. From the log for that test (attached),
it appears that it tries to split the region 3 times instead of just once.
> I did see the error:
>     [junit] Exception in thread "HMaster.metaScanner" java.lang.IllegalArgumentException:
Can't build a writable with empty bytes array
>     [junit] 	at org.apache.hadoop.hbase.util.Writables.getWritable(Writables.java:77)
>     [junit] 	at org.apache.hadoop.hbase.HMaster$BaseScanner.scanRegion(HMaster.java:272)
>     [junit] 	at org.apache.hadoop.hbase.HMaster$MetaScanner.scanOneMetaRegion(HMaster.java:602)
>     [junit] 	at org.apache.hadoop.hbase.HMaster$MetaScanner.maintenanceScan(HMaster.java:659)
>     [junit] 	at org.apache.hadoop.hbase.HMaster$BaseScanner.run(HMaster.java:175)
>     [junit] 	at java.lang.Thread.run(Thread.java:595)
> and afterwards there were no reports from the metaScanner so this may be related to HADOOP-1730
