The files are viewable from hdfs as:

Found 1 items
-rw-r--r-- 3 hadoopqa hdfs 209607 2011-07-05 06:54
/data/singlefile/studentnulltab10k
Mount side table:
/user/hadoopqa/pig/tests/data is mounted as /data
Additional Comments:
Regression suites pass on dotNext when mount side tables are not configured.
