Dumindu Buddhika updated PHOENIX-777:
-------------------------------------
Description:
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.
