Prashant,
I can't find such an udf in piggybank. Yes, I think this is going to be
useful for many users.
I would be great if you can contribute such udfs to piggybank.
Thanks,
Thejas

Is there a UDF that could be used to check if a string is numeric (or an
Integer). This would be nice to have (if we don't already) as part of
Piggybank.
A lot of other tools such as Splunk, AbInitio have this UDF built-in and I
know companies are making an effort to move to Hadoop/Pig which could use
this.
Use Case:
In raw logs there are certain filters/conditions applied based on whether a
particular field/value is numeric or not. For eg, SPLIT A INTO CATEGORY1 IF
IsInt($0), CATEGORY2 IF !IsInt($0);
Thoughts?
