[jira] [Comment Edited] (FLINK-15641) Support to start sidecar
container and init container
[ https://issues.apache.org/jira/browse/FLINK-15641?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17027369#comment-17027369 ]

------------------------------------------------------------
I think this ticket is lacking focus (can be at least two tickets), and it is underspecified.
{quote}Add a sidecar container of FlinkMaster and TaskManager to collector log to shared storage(hdfs, elastic search, etc.).{quote}
How can we achieve technology-agnostic log upload?
{quote}Use init container to download users jars dynamically or do something else before start jobmanager and taskmanager.{quote}
What does this mean? Why would this be beneficial? Can it be also used in standalone mode, or is it specific to k8s?
