Richard Ding commented on PIG-1551:
-----------------------------------
The typo is still there:
{code}
private static final Class<?> LONG_ARRAY_CLASS = new Long[0].getClass();
{code}
It seems what you want is
{code}
private static final Class<?> LONG_ARRAY_CLASS = new long[0].getClass();
{code}
so it's consistent with other array classes.
This does raise a question about array parameters: the first form applies to
methods like _amethod(Long[] nums)_, while the second supports methods like
_amethod(long[] nums)_. And they are not exchangeable.

> PIG-1354 introduced a set of UDFs that can be used to dynamically wrap simple
> Java methods in a UDF, so that users don't need to create trivial wrappers if
> they are ok sacrificing some speed.
> This issue is to extend the set of methods that can be wrapped this way to
> include methods that do not take any arguments, and methods that take arrays
> of {int,long,float,double,string} as arguments.
> Arrays are expected to be represented by bags in Pig. Notably, this allows
> users to wrap statistical functions in o.a.commons.math.stat.StatUtils .
