[jira] [Created] (YARN-8839) Define a protocol exchange between
websocket client and server for interactive shell
Eric Yang created YARN-8839:
-------------------------------
Summary: Define a protocol exchange between websocket client and server for interactive shell
Key: YARN-8839
URL: https://issues.apache.org/jira/browse/YARN-8839
Project: Hadoop YARN
Issue Type: Sub-task
Components: nodemanager
Reporter: Eric Yang
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.
