---------------------------------
Summary: Remove sync client implementation and wrap async client
under sync client interface
Key: HBASE-18334
URL: https://issues.apache.org/jira/browse/HBASE-18334
Project: HBase
Issue Type: Task
Reporter: Phil Yang
Fix For: 3.0.0
Since 2.0 we have async client, now we have two client implementations. We can
implement an sync client by using async client, getting a CompletableFuture and
then waiting it done directly. This can reduce the maintenance work at client
side.
Async client is almost done, we have test the performance and it showed it has
same performance with sync client. In branch-2 we can keep old sync client
implementations and remove it in master branch (since 3.0).
