    [ https://issues.apache.org/jira/browse/FLINK-22137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17680263#comment-17680263 ] 

Anton Kalashnikov commented on FLINK-22137:
-------------------------------------------

I don't remember why we didn't close this ticket. But considering that the parent ticket is closed already I think we can close this ticket as well.

Any objections? [~arvid]

> Start application and at some point cancel/induce failure, the user needs to restart from a retained checkpoint with
> *     lower
> *     same
> *     higher degree of parallelism.
> To enable unaligned checkpoints, set
> *     execution.checkpointing.unaligned: true
> *     execution.checkpointing.alignment-timeout to 0s, 10s, 1min (for high backpressure)
> The primary objective is to check if all data is recovered properly and if the semantics is correct (does state match input?).
> The secondary objective is to check if Flink UI shows the information correctly:
> *     unaligned checkpoint enabled on job level
> *     timeout on job level
> *     for each checkpoint, if it's unaligned or not; how much data was written
