Ashu Pachauri updated HBASE-16752:
----------------------------------
Attachment: HBASE-16752.V2.patch
V2: Close the connection after making sure we send the response for the
offending rpc to the client. Also, adding javadoc for the
RequestTooBigException.
> Upgrading from 1.2 to 1.3 can lead to replication failures due to difference
> in RPC size limit

> Key: HBASE-16752
> URL: https://issues.apache.org/jira/browse/HBASE-16752
> Project: HBase
> Issue Type: Bug
> Components: Replication, rpc
> Affects Versions: 2.0.0, 1.3.0
> Reporter: Ashu Pachauri
> Assignee: Ashu Pachauri

> In HBase 1.2, we don't limit size of a single RPC but in 1.3 we limit it by
> default to 256 MB. This means that during upgrade scenarios (or when source
> is 1.2 peer is already on 1.3), it's possible to encounter a situation where
> we try to send an rpc with size greater than 256 MB because we never unroll a
> WALEdit while sending replication traffic.
> RpcServer throws the underlying exception locally, but closes the connection
> with returning the underlying error to the client, and client only sees a
> "Broken pipe" error.
> I am not sure what is the proper fix here (or if one is needed) to make sure
> this does not happen, but we should return the underlying exception to the
> RpcClient, because without it, it can be difficult to diagnose the problem,
> especially for someone new to HBase.
