Johannes Zillmann updated PIG-137:
----------------------------------
Attachment: PIG-137-633746.patch
Oh, i think this case it has nothing to do with the logging. Its just about the
exception conversion, where informations simply getting lost.
I've uploaded a patch for this case (simply removed the try-catch, since there
can be only RuntimeException, which did not need to be wrapped or converted to
IOExceptions).
The stacktrace without the patch:
{noformat}
java.io.IOException: could not instantiate 'com.my.DatabaseStoreFunc' with
arguments 'aDb, table'
