Subject [jira] [Commented] (HADOOP-10940) RPC client does no bounds checking of responses
Date Fri, 09 Sep 2016 14:33:22 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10940?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15477190#comment-15477190

Kihwal Lee commented on HADOOP-10940:
-------------------------------------

The patch looks good in general. We have also been running it in production internally for
quite a while.
One nit. The new config variable needs to be added/documented in {{core-default.xml}}.

> The rpc client does no bounds checking of server responses.  In the case of communicating
with an older and incompatible RPC, this may lead to OOM issues and leaking of resources.
