Daniel Dai commented on PIG-4156:
---------------------------------
Does this alone fix your issue? When the script is on hdfs, Pig assumes all
register jar without full scheme is also on hdfs, including the hive/hcat jars
brought by -useHCatalog. So once we fix NPE, does Pig end up with file not
found exception?
> [PATCH] fix NPE when running scripts stored on hdfs://
