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

             Summary: Protocol version mismatch in case of a long password
                 Key: IGNITE-17387
                 URL: https://issues.apache.org/jira/browse/IGNITE-17387
             Project: Ignite
          Issue Type: Bug
          Components: thin client
            Reporter: Igor Sapego
            Assignee: Igor Sapego


If user specifies a password longer than 64k (with the default conf) we get a protocol mismatch error:

org.apache.ignite.internal.client.thin.ClientProtocolError: Protocol version mismatch: client 1.7.0 / server 2.8.0. Server details: Unsupported version: 1.0.0

It happens because of the overflow of socket send buffer (limit is 64K see https://docs.oracle.com/javase/7/docs/api/java/net/ServerSocket.html#setReceiveBufferSize(int) ).

So WA is to extend default socket buffers size and add limitation to their passwords sizes (e.g restrict max password size to 32K).

// if password is about 60K it will be OK for default config, if more than 64K you will receive version protocol error (because 
// TcpClientChannel would read wrong data from buffer). Here we extend default buffer sizes to 100K to bypass this issue.

new ClientConnectorConfiguration()
                    .setSocketSendBufferSize(100 * 1024)
                    .setSocketReceiveBufferSize(100 * 1024)
