Two more questions here, # Should we give user sone kind of notification while NM restart and we are trying to resuming the docker exec? What if we get several retries to reconnect and don't succeed? We may need to give user some friendly reminder to avoid the misunderstanding of session been stuck for too long, right? # How to handle NM unexpected shutdown(like crash, etc) scenario? > Interactive docker shell > ------------------------ > > Key: YARN-8523 > URL: https://issues.apache.org/jira/browse/YARN-8523 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Eric Yang > Priority: Major > Labels: Docker > > Some application might require interactive unix commands executions to carry out operations. Container-executor can interface with docker exec to debug or analyze docker containers while the application is running. It would be nice to support an API to invoke docker exec to perform unix commands and report back the output to application master. Application master can distribute and aggregate execution of the commands to record in application master log file. -- 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
