------------------------------
Summary: [ORC]if map.value is selected, map.key should be selected
automatically to prevent segment fault.
Key: ORC-800
URL: https://issues.apache.org/jira/browse/ORC-800
Project: ORC
Issue Type: Improvement
Reporter: Zherui Cao
Assignee: Zherui Cao
Some Tools querying map as a struct so map.key and map.value is independent.
But either way map is selected. Then MapVectorBatch is accessible, once
MapVectorBatch is accessible,
MapVectorBatch::toString will definitely encounter segment fault due to map.key
is not selected if we only select map.value.
