For enabling terminal based program to run, there are certain functions that work outside of stdio streams to the destination program. A couple known functions to improve terminal usability: > # Resize terminal columns and rows > # Set title of the window > # Upload files via zmodem protocol > # Set terminal type > # Heartbeat (poll server side for more data) > # Send keystroke payload to server side > If we want to be on parity with commonly supported ssh terminal functions, we need to develop a set of protocols between websocket client and server. Client and server intercept the messages to enable functions that are normally outside of the stdio streams. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
