[jira] [Commented] (HADOOP-12579) Deprecate and remove WriteableRPCEngine

    [ https://issues.apache.org/jira/browse/HADOOP-12579?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15184079#comment-15184079 ] 

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

Note HADOOP-12819 is ready for review. When it's in, I thought all the left test migrating work plus the removal of the old engine can be done here in a patch in reasonable size.

> 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.
