[jira] [Commented] (YARN-5082) ContainerId rapidly increased in
fair scheduler if the num of node app reserved reached the limit
[ https://issues.apache.org/jira/browse/YARN-5082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15282911#comment-15282911 ]
sandflee commented on YARN-5082:
--------------------------------
we enable continuous scheduling, so containerID increased (corresponding to a container creation) at every schedule period. create a container only when container could be allocated or container reserved at first time seems more reasonable.
