Koji Noguchi updated PIG-3447:
------------------------------
Attachment: pig-3447-v01.txt
With the patch, it'll print out
{noformat}
2013-09-03 13:58:20,625 [main] WARN org.apache.pig.PigServer - Encountered
Warning NO_LOAD_FUNCTION_FOR_CASTING_BYTEARRAY 1 time(s).
{noformat}
If anyone still calls CompilationMessageCollector.collect without enum KIND,
then it'll at least print out
{noformat}
2013-08-30 22:25:20,940 [main] WARN org.apache.pig.PigServer - Encountered
Warning Aggregated unknown kind messages. Please set -Daggregate.warning=false
to retrieve these messages 1 time(s).
{noformat}
Before, it wasn't printing out anything.
With -Daggregate.warning=false, it'll print out the following (even without
this patch).
{noformat}

load function to use for casting from bytearray to chararray.
