-------------------------------
Looks like hadoop-1730 to me. Waiting on tests before committing it.

> 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
