Alan Gates commented on PIG-144:
--------------------------------
I don't think we have to suggest alternate spellings. But surely we can do
better than exposing the internal state of the parser (decision=2 state 6). We
could at least give a message like: "expected keyword found identifier" or
"malformed line at _linnum_ 'B = tream ...'"
> The error message should be more meaningful when there is a typo in PIg script

> When I ran the following Pig script on the command line {{"pig -c mycluster
> myscript.pig"}}, I got the error:
> 2008-03-07 16:31:45,992 [main] ERROR org.apache.pig.tools.grunt.Grunt -
>
> {code}
> A = load '/user/pig/tests/data/singlefile/fileexists';
> B = foreach A generate $2, $1, $0;
> C = strean B through `awk '{print $3 " " $4 "\t" $2 "\t" $1}'`;
> store C into '/user/pig/tests/data/singlefile/results1';
> {code}
> The error message is not quite meaningful, and it took me a while to find out
> what was wrong - the word "strean" should have been "stream".
