Kai Zheng commented on HADOOP-12579:
------------------------------------

The failed tests are not relevant. The remained check styles are not suitable to be fixed.
The patch is ready for review.

> The {{WriteableRPCEninge}} depends on Java's serialization mechanisms for RPC requests.
Without proper checks, it has be shown that it can lead to security vulnerabilities such as
remote code execution (e.g., COLLECTIONS-580, HADOOP-12577).
> The current implementation has migrated from {{WriteableRPCEngine}} to {{ProtobufRPCEngine}}
now. This jira proposes to deprecate {{WriteableRPCEngine}} in branch-2 and to remove it in
trunk.
