Hari Sankar Sivarama Subramaniyan updated HIVE-5202:
----------------------------------------------------
Description:
These 3 tasks should be accomplished as part of the following jira:
1. The current implementation lacks settable union object inspector. We can run
into exception inside ObjectInspectorConverters.getConvertedOI() if there is a
union.
2. Implement the following public functions for all datatypes:
isSettable()-> Perform shallow check to see if an object inspector is inherited
from settableOI type and
hasAllFieldsSettable() -> Perform deep check to see if this objectInspector and
all the underlying object inspectors are inherited from settableOI type.
3. ObjectInspectorConverters.getConvertedOI() is inefficient. Once (1) and (2)
are implemented, add the following check: outputOI.hasAllSettableFields()
should be added to return outputOI immediately if the object is entirely
settable in order to prevent redundant object instantiation.
