[hbase] Region split broken
---------------------------

                 Key: HADOOP-1734
                 URL: https://issues.apache.org/jira/browse/HADOOP-1734
             Project: Hadoop
          Issue Type: Bug
          Components: contrib/hbase
    Affects Versions: 0.15.0
            Reporter: Jim Kellerman
            Assignee: stack
             Fix For: 0.15.0
         Attachments: console.txt

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
