Zian Chen created YARN-8763: ------------------------------- Summary: Add WebSocket logic to the Node Manager web server to establish servlet Key: YARN-8763 URL: https://issues.apache.org/jira/browse/YARN-8763 Project: Hadoop YARN Issue Type: Sub-task Reporter: Zian Chen Assignee: Zian Chen
The reason we want to use WebSocket servlet to serve the backend instead of establishing the connection through HTTP is that WebSocket solves a few issues with HTTP which needed for our scenario, # In HTTP, the request is always initiated by the client and the response is processed by the server — making HTTP a unidirectional protocol, while web socket provides the Bi-directional protocol which means either client/server can send a message to the other party. # Full-duplex communication — client and server can talk to each other independently at the same time # Single TCP connection — After upgrading the HTTP connection in the beginning, client and server communicate over that same TCP connection throughout the lifecycle of WebSocket connection -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
