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. > 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 > Assignee: Eric Yang > Priority: Major > Labels: docker > > 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. -- 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
