[jira] [Commented] (YARN-8447) Support configurable IPC mode in
docker runtime
[ https://issues.apache.org/jira/browse/YARN-8447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16742956#comment-16742956 ]
Namrata Pawale commented on YARN-8447:
--------------------------------------
I have a mapreduce program that communicates with a process on localhost machine. When running this job using yarn docker containers, the job fails because the container fails to communicate with the process. I tried running the same job without launching docker container from yarn but using docker run and specifying --ipc="host" and it worked.
The detailed use case will be updated soon.
