> UDF that could be used to check if a String is numeric (or an Integer). Several tools
such as Splunk, AbInitio have this UDF built-in and companies making an effort to move to
Hadoop/Pig 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);
