Eli Levine commented on CALCITE-1561: ------------------------------------- Did a bunch more digging and as far as I can tell this is due to the fact that PigTest's local Pig execution mode cannot read data files. Why it happens sporadically I could not determine, since I could never consistently repro. I have added some code to make PigTest's cluster aware of the files. Let's see if it improves things.
