[jira] [Comment Edited] (FLINK-29660) Show all attempts of subtasks in WebUI

["Zhu Zhu (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-29660?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17624818#comment-17624818 ]

-----------------------------------------------------------

In the exception history, it already shows all the root exceptions and the concurrent exceptions. You can also check any concurrent exception by filtering the task name if you think the displayed root cause is not the true root.

Showing all attempts on the vertex tab may result in performance problem because there can be too many attempts to be retrieved and shown at one time, given that tasks may failover multiple times. At the moment, the tab can be slower and harder to navigate if the parallelism is large and I prefer not to add much extra burden to it.

Maybe a better way is to show the task manager id on the exception history page, and a link to the task manager id to jump to the task manager page.
