             Summary: Create Subarray UDF
                 Key: HIVEMALL-231
                 URL: https://issues.apache.org/jira/browse/HIVEMALL-231
             Project: Hivemall
          Issue Type: Improvement
    Affects Versions: 0.6.0
            Reporter: Makoto Yui
            Assignee: Makoto Yui
             Fix For: 0.6.0


subarray(array, fromIndex, length) currently uses ArraySliceUDF introduced by 
Brickhouse function.

But, it brokes backward compatibility of old subarray UDF of signature 
subarray(array, fromIndex, toIndexExclusive).

So, create SubarrayUDF and replace subarray implementation with it.
