Harry Y commented on PIG-212:
-----------------------------
I'm very new to Pig, and I encounter this type of problem quite frequently. I
haven't really looked at the code, but it appears that the Pig processor and
the shell is not cleanly separated. When errors like TokenMgrError (which I
presume a runtime error rather than an exception from the name) is thrown,
there might not be much the Pig prcessor can do and it may be reasonable to
just bail out. However, the grunt shell should be able to catch this type of
non-fatal errors ("non-fatal" as far as Grunt is concerned) rather than just
crash. I could be completely off here, but I suspect that this can be easily
fixed by slightly modifying the high-level logic (e.g., regarding how grunt
calls/spawns the pig "module", if there is such a thing).
