Thomas Memenga commented on PIG-240:
------------------------------------
Any news on this? We are trying to trigger a lot of pig-jobs simultaneously
from a single jvm and we are recieving "Unable to find clone for op" errors
from time to time (pig 0.8.0). It's a pitty PigServer isn't threadsafe,
spawning jvms for each script seems to be our only option.
