Igor Sapego created IGNITE-17387: ------------------------------------ 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) -- This message was sent by Atlassian Jira (v8.20.10#820010)
