What's your Hadoop & HBase version??
The line at
org.apache.hadoop.hbase.mapreduce.HFileOutputFormat2.configurePartitioner(HFileOutputFormat2.java:545)
is
Path partitionsPath = new Path("/tmp", "partitions_" + UUID.randomUUID());
which is impossible to produce any null value. My feeling is mismatch of
software versions.
