----------------------------------------------------------

my environment is like below:
   hadoop2.6.0 
   hive0.14.0
   hbase0.98
   zookeeper3.4.6
those components are installed alone, not use the sandbox.

I also  tracked the source code, and find org.apache.hadoop.hbase.mapreduce.HFileOutputFormat2.configurePartitioner(HFileOutputFormat2.java:545)
is
Path partitionsPath = new Path("/tmp", "partitions_" + UUID.randomUUID());
which is indeed impossible to produce any null value. And can't find out environmental problems.
