> HBASE-13010 changed hard-coded '/tmp' in HFileOutputFormat2 partitioner's path to 'hadoop.tmp.dir'.
 This breaks unit test in Windows.
> {code}
>    static void configurePartitioner(Job job, List<ImmutableBytesWritable> splitPoints)
>      ...
>      // create the partitions file
> -    FileSystem fs = FileSystem.get(job.getConfiguration());

> {code}
> Here is the exception from 1 of the UTs when running against Windows (from branch-1.1)
- The ':' is an invalid character in windows file path:
