> Disk entries of names prefixed with '_' is excluded during split generation, and should
be excluded from CG's data file processing too. Furthermore, FileInputFormat treats those
files as hidden files. Zebra should ignore them to be safe.
> At writing, zebra creates _temporary directory under the table (PIG-1115). The directory
may not be totally cleaned up due to lagging speculative executions. To avoid  any confusions
resulting from attempt to access the _temporary directory, the disk entries of names with
the '_' prefix should also be excluded by Zebra processing.
> On the other hand, now that Zebra's pig tests run much faster using PIG's local mode,
all pig-related should be included in the "pigtest" target to complete PIG's test coverage.
