Ashutosh Chauhan commented on PIG-1531:
---------------------------------------
Another instance where it happens is when input location doesnt exists, error
message shown is
{code}
org.apache.pig.backend.executionengine.ExecException: ERROR 2118: Unable to
create input splits for tmp_emtpy_1280539088
{code}
Whereas underlying exception did have more useful String which gets lost in log
file
{code}
org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does
not exist:
hdfs://machine.server.edu/tmp/pig/tmp_tables/tmp_empty_1280539088
{code}
> Pig gobbles up error messages

> Key: PIG-1531
> URL: https://issues.apache.org/jira/browse/PIG-1531
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.7.0
> Reporter: Ashutosh Chauhan
> Assignee: niraj rai
> Fix For: 0.8.0
>
>
> Consider the following. I have my own Storer implementing StoreFunc and I am
> throwing FrontEndException (and other Exceptions derived from PigException)
> in its various methods. I expect those error messages to be shown in error
> scenarios. Instead Pig gobbles up my error messages and shows its own generic
> error message like:
> {code}
> 010-07-31 14:14:25,414 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
> 2116: Unexpected error. Could not validate the output specification for:
> default.partitoned
> Details at logfile: /Users/ashutosh/workspace/pig/pig_1280610650690.log
> {code}
> Instead I expect it to display my error messages which it stores away in that
> log file.
