SteNicholas opened a new pull request #15732:
URL: https://github.com/apache/flink/pull/15732
## What is the purpose of the change
*Currently we have already have the Rest API /jobs/:jobid/checkpoints/config
that returns the statebackend name and checkpoint storage type:*
```
{
"mode":"exactly_once",
"interval":20,
"timeout":600000,
"min_pause":0,
"max_concurrent":1,
"externalization":{
"enabled":false,
"delete_on_cancellation":true
},
"state_backend":"EmbeddedRocksDBStateBackend",
"checkpoint_storage":"FileSystemCheckpointStorage",
"unaligned_checkpoints":false,
"tolerable_failed_checkpoints":0
}
```
*But the two fields does not shown in the Web UI of checkpoint
configuration. `job-checkpoints.component.html` should add the above mentioned
fields for show.*
## Brief change log
- *`job-checkpoints.component.html` adds two rows for the show of
`state_backend` and `checkpoint_storage` fields.*
