Zhihua Deng updated HIVE-29402:
-------------------------------
Summary: Split the complex operation from HMSHandler (was: Decouple the
complex operation from HMSHandler)
> Split the complex operation from HMSHandler
> -------------------------------------------
>
> Key: HIVE-29402
> URL: https://issues.apache.org/jira/browse/HIVE-29402
> Project: Hive
> Issue Type: Wish
> Reporter: Zhihua Deng
> Priority: Major
>
> In older versions, the HMSHandler is a "God Object" that handled everything
> from Thrift requests and authorization to file system operations and raw
> database transactions.
> To decouple these operations from HMSHandler, HIVE-27224 introduces the
> AbstractOperationHandler, where a handler can deal with a specific request,
> it handles the file system operations, transactions and notifying the
> listener reacting to this request only, the HMSHandler takes care of the
> rest, such as audit, exception and the respond to the client.
> By this way the HMSHandler has a simpler routine, which makes it easier to
> maintain and optimize in the future.
