Thejas M Nair commented on HIVE-11527:
--------------------------------------
[~tasanuma0829] I think it makes sense to explore if we can extend typeDesc to
encode the fully information for complex types. Otherwise, we have duplicate
information being sent.
([~prasadm] [~cwsteinbach] please chime in if you have tried that ).
The serliazation format is hardcoded in this case. If we use a single serde
format, using LazyBinarySerDe instead of LazySimpleSerde is likely to be more
performant IMO. [~gopalv] What are your thoughts on that ?
> bypass HiveServer2 thrift interface for query results

> Right now, HS2 reads query results and returns them to the caller via its
> thrift API.
> There should be an option for HS2 to return some pointer to results (an HDFS
> link?) and for the user to read the results directly off HDFS inside the
> cluster, or via something like WebHDFS outside the cluster
