Description

Hi all,
When I run a native MR job with the MAPREDUCE keyword and store the intermediate data in HBase with:
stored = MAPREDUCE 'my.jar'
STORE x INTO 'hbase://temp_table'
USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('hbase_schema')
.... and the rest ....;

Pig tries to delete the temp files, which in this case has an HBase path, and fails with the exception:

Caused by: java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: file:hbase:/temp_table
