[jira] [Commented] (HBASE-15212) RRCServer should enforce max request size

    [ https://issues.apache.org/jira/browse/HBASE-15212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15222357#comment-15222357 ]

---------------------------------------

bq. Seems this cause TestAsyncIPC.testRpcMaxRequestSize fail?
I've ran that test locally before commit (see https://issues.apache.org/jira/browse/HBASE-15212?focusedCommentId=15207492&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15207492). It seemed like a flaky test (because I've seen the failure before this if I remember right). But maybe there is an issue.

> A TODO from HBASE-15177 was that we are not protecting the RPCServer in case an RPC request with a very large size is received. This might cause the server to go OOM because we are allocating the RPC serialization into a BB. Instead we should reject the RPC and close the connection.
