Review Comment:
   Unaligned checkpoint or change log state backend are enabled in the 
`TestStreamEnvironment#randomizeConfiguration`. And I see a large number of 
tests calling `FsStateChangelogStorageFactory.configure()` to Configure DFS 
DSTL in FLINK-23279, including: 
`StateChangelogOptions.STATE_CHANGE_LOG_STORAGE` and 
`FsStateChangelogOptions.BASE_PATH`. 
   
   If we are worried about increasing the running time, we can set 
`CheckpointingOptions.CHECKPOINT_STORAGE` and 
`CheckpointingOptions.CHECKPOINTS_DIRECTORY` in a similar way, what do you 
think?
