    Resolution: Duplicate

I'm closing this, as it's another symptom of the same problem described in FLINK-17012. There is a discussion about the potential solution [here|https://issues.apache.org/jira/browse/FLINK-17012?focusedCommentId=17091539&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17091539]

> {{CheckpointCoordinator}} will start triggering checkpoint after all tasks send RUNNING status to JobMaster. However, the {{initializeState}} could be time-expensive(a few minutes), for example the task needs to rescale with multiple old tasks' rocksdb data. During this process, the triggering of checkpoints are meaningless.
