[jira] [Resolved] (YARN-8839) Define a protocol exchange between websocket client and server for interactive shell

     [ https://issues.apache.org/jira/browse/YARN-8839?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Yang resolved YARN-8839.
-----------------------------
    Resolution: Fixed

No change the proposed protocol for a while, and this has been implemented for heartbeat.  Close as resolved.

> Running interactive shell is more than piping stdio from docker exec through a web socket.  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.
