---------------------------------------------------------------------
[~kgyrtkirk] My bad, I noticed the green tick in the title and assumed the
tests are passed but missed the "tests-failed" tag.
Thanks for reverting the patch!
[~warriersruthi], Could you pls resubmit the patch and fix those test failures?

> Support Map data-type natively in Arrow format

> Key: HIVE-25553
> URL: https://issues.apache.org/jira/browse/HIVE-25553
> Project: Hive
> Issue Type: Improvement
> Components: llap, Serializers/Deserializers
> Reporter: Adesh Kumar Rao
> Assignee: Sruthi Mooriyathvariam
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0

> Time Spent: 2h 40m
> Remaining Estimate: 0h

> Currently ArrowColumnarBatchSerDe converts map datatype as a list of structs
> data-type (where stuct is containing the key-value pair of the map). This
> causes issues when reading Map datatype using llap-ext-client as it reads a
> list of structs instead.
> HiveWarehouseConnector which uses the llap-ext-client throws exception when
> the schema (containing Map data type) is different from actual data (list of
> structs).
>
> Fixing this issue requires upgrading arrow version (where map data-type is
> supported), modifying ArrowColumnarBatchSerDe and corresponding
> Serializer/Deserializer to not use list as a workaround for map and use the
> arrow map data-type instead.
