embedded Pig using PigServer

Hi,

I have some issues in using embedded Pig using PigServer. I used
AvroStorage() to store data into the local disk and Eclipse for debugging.
When I debug the program by setting some breakpoints and using the local
mode. I found that, initially, there was a directory, _temporary, created
in the file path that was supposed to save the processed data using
AvroStorage(). But at the end of the run, the directory _temporary got
deleted, nothing was saved, and the job failed. Any suggestion on how to
resolve the issue? Thanks.
