Subject [jira] [Commented] (HBASE-15212) RRCServer should enforce max request size
Date Fri, 05 Feb 2016 05:01:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15133663#comment-15133663

ramkrishna.s.vasudevan commented on HBASE-15212:
------------------------------------------------

I think sooner we will be moving over to Offheap Memstore and offheap in write path. I think
once that happens we have to fine tune other parameters also like flush related params as
many of that are dependent on the heap Xmx which may become irrelevant to an extent once we
go to Offheap.

> 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.
