Subject [jira] [Commented] (HADOOP-12579) Deprecate and remove WriteableRPCEngine
Date Tue, 27 Sep 2016 22:17:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12579?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15527574#comment-15527574

Kai Zheng commented on HADOOP-12579:

In MAPREDUCE-6706 [~djp] had a [comment|https://issues.apache.org/jira/browse/MAPREDUCE-6706?focusedCommentId=15500791&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15500791]
that the old RPC engine WriteableRPCEngine might be still used by other projects like Tez.
Considering this I'd re-target this as only {{deprecate}} rather than {{removal}} of the engine.
Please correct if you'd think otherwise. Thanks.

> 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
