Zakelly Lan updated FLINK-33057:
--------------------------------
Description: By default, Flink creates subdirectories named by UUID (job
id) under checkpoint directory for each job. It's a good means to avoid
collision. However, it also bring in some effort to remember/find the right
directory when recovering from previous checkpoint. According to previous
discussion ([Yun
Tang's|https://issues.apache.org/jira/browse/FLINK-11789?focusedCommentId=16782314&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16782314]

subdirectories under the checkpoint directory. For compatibility
considerations, we create the subdirectories by default. (was: By default,
