Subject [jira] [Updated] (HBASE-12668) Adapt PayloadCarryingRpcController so it can also be used in async way
Date Wed, 10 Dec 2014 14:16:12 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12668?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jurriaan Mous updated HBASE-12668:
----------------------------------
    Attachment: HBASE-12668.patch

- Implemented the necessary methods in PayloadCarryingRpcController and TimeLimitedRpcController.
- Added an setFailed with exception method to TimeLimitedRpcController so it is easier to
pass on exceptions.
- Moved out BlockingRpcChannelImplementation and createBlockingRpcChannel method from RpcClientImpl
into AbstractRpcClient since they can now be used in an async client. It contains an abstract
call method to implement for blocking calls. This saves duplicated code on new RpcClient implementations.

> With the changes in HBASE-12597 it is possible to create a new RPC client. But in all
places the BlockingRpcChannel is called with a PayloadCarryingRpcController. This controller
is not usable in Async context because some methods are not supported at the moment. (See
TimeLimitedRpcController for the methods that throw UnsupportedOperationException)
> This issue is about implementing these methods so PayloadCarryingRpcController can also
be used in an async context and work the same in a sync context.
