>          Issue Type: Bug
>          Components: thin client
>    Affects Versions: 2.13
>            Reporter: Igor Sapego
>            Assignee: Igor Sapego
>            Priority: Major

> If user specifies a password longer than 64k (with the default conf) we get a protocol mismatch error:
> {code}
> 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
> {code}
> 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).
> {code}
> // 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)
> {code}
