Subject [jira] [Commented] (PHOENIX-777) Support null value for fixed length ARRAY
Date Tue, 02 Jun 2015 05:58:18 GMT

ramkrishna.s.vasudevan commented on PHOENIX-777:
------------------------------------------------

Pushed to master, 4.x and 4.4 branches as this patch is a bug fix.  The implementation of
handling nulls can go to 4.5.x branches alone when we do that JIRA.
Thanks for the patch [~Dumindux]. Thanks for the reviews and feed back [~alexdl], [~kathir]
and finally [~giacomotaylor].

> 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.
