> Within some contexts, the parser fails to treat semicolons correctly, and sees them as
an EOL.
> Given an input file:
> /test1.txt (in the hdfs)
> 1;a
> 2;b
> 3;c
> 4;d
> 5;e
> And the following Pig script:
> REGISTER /tmp/piggybank.jar ;
> DEFINE REGEXEXTRACTALL org.apache.pig.piggybank.evaluation.string.RegexExtractAll();
> lines = LOAD '/test1.txt' AS (line:chararray);
> delimited = FOREACH lines GENERATE FLATTEN (
>         REGEXEXTRACTALL(line, '^(\\d+);(\\w+)$')
> ) AS (
>         digit:int,
>         word:chararray
> );
> DUMP delimited;
> I receive the following error:
> ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1000: Error during parsing. Lexical error
at line 5, column 40.  Encountered: <EOF> after : "\'^(\\\\d+);"
