------------------------------------
[~ram_krish] and [~Dumindux] the patch would be helpful as is
[~jamestaylor] if we reserve a special value for "null" on application side we
need to replace all the functions (sum, avg etc) with UDFs that ignore that
special value in computing the result, which is kind of ugly
> Support null value for fixed length ARRAY

>
> A null value for a fixed length array can be handled with a bitset tacked on
> the end of the array. If an element is set to null, then the bit at that
> index is set. Trailing nulls are not stored and an attempt to access an array
> past the current size returns null.
> Current behavior,
> PBinaryArray - Throws an exception when a null is inserted.
> PBooleanArray - null is considered as false when a null is inserted.
> PCharArray - Throws an exception when a null is inserted.
> PDateArray - Throws an exception when a null is inserted.
> PDoubleArray - null is considered as 0.0 when a null is inserted.
> PFloatArray - null is considered as 0.0 when a null is inserted.
> PIntegerArray - null is considered as 0 when a null is inserted.
> PLongArray - null is considered as 0 when a null is inserted.
> PSmallIntArray - null is considered as 0 when a null is inserted.
> PTimeArray - Throws an exception when a null is inserted.
> PTimeStampArray - Throws an exception when a null is inserted.
> PTinyIntArray - null is considered as 0 when a null is inserted.
