[jira] [Comment Edited] (FLINK-22243) Reactive Mode parallelism changes are not shown in the job graph visualization in the UI
[ https://issues.apache.org/jira/browse/FLINK-22243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17500119#comment-17500119 ]

[~zhuzh] mentioned a possible solution in FLINK-26400:
{quote}I guess the root cause is the json plan is not updated on job vertex parallelism changes. Because we encountered the same issue when developing AdaptiveBatchScheduler. As a reference, our solution can be found [here|https://github.com/apache/flink/blob/152ad4fc14920372076c0004793c179141ae10c7/flink-runtime/src/main/java/org/apache/flink/runtime/scheduler/adaptivebatch/AdaptiveBatchScheduler.java#L224].{quote}
