> make HS2 core components re-usable across projects

> Key: HIVE-11968
> URL: https://issues.apache.org/jira/browse/HIVE-11968
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Reporter: Thejas M Nair
>
> HS2 provides jdbc and odbc access to hive. There has been a lot of investment
> into HS2 over time ( Fault tolerance, authentication modes, HTTP transport
> mode, encryption, delegation tokens .. ).
> The thrift API that HS2 provides is generic and is applicable to other SQL
> engines as well. Spark is already using a fork of HS2, but as it is a fork,
> it hard to maintain.
> HS2 code is not structured to be easily re-used and extended. If we can make
> improvements there, it can be easily re-used by other projects, and all
> effort can be combined.
