Subject [jira] [Updated] (HIVE-5202) Support for SettableUnionObjectInspector and implement isSettable/hasAllFieldsSettable APIs for all data types.
Date Tue, 17 Sep 2013 02:01:53 GMT

     [ https://issues.apache.org/jira/browse/HIVE-5202?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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() and hasAllFieldsSettable()
3. ObjectInspectorConverters.getConvertedOI() is inefficient. Once (1) and (2) are implemented,
the following check: outputOI.hasAllSettableFields() should be added to return outputOI immediately
if the object is entirely settable inorder to prevent redundant object instantiation.  

  was:The current implementation lacks settable union object inspector. We can run into exception
inside ObjectInspectorConverters.getConvertedOI() if there is a union.

        Summary: Support for SettableUnionObjectInspector and implement isSettable/hasAllFieldsSettable
