Subject [jira] [Commented] (HADOOP-12579) Deprecate and remove WriteableRPCEngine
Date Fri, 15 Jan 2016 02:13:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12579?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15101062#comment-15101062

Haohui Mai commented on HADOOP-12579:
-------------------------------------

I consider {{WritableRPCEngine}} is dead code. I suggest cleaning up the tests instead of
putting a major functionality ({{WirtableRPCEngine}} in the tests.

> 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.
