[jira] [Comment Edited] (YARN-9245) Add support for Docker Images
command
[ https://issues.apache.org/jira/browse/YARN-9245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16764010#comment-16764010 ]

---------------------------------------------------------
[~csingh] Thank you for the patch. Patch 002 looks ok. When the delimiter is : character, some images may not split at expected character due to port number:
{code}
host-1.example.com:5000/centos:latest
centos:7
{code}
It might be better to use {{json .}} to ensure the output serialization doesn't get processed incorrectly. It is good to control the output format in container executor to prevent upstream input error to generate bad output down stream.
