>
> Key: FLINK-8916
> URL: https://issues.apache.org/jira/browse/FLINK-8916
> Project: Flink
> Issue Type: Bug
> Components: REST
> Affects Versions: 1.5.0, 1.6.0
> Reporter: Gary Yao
> Assignee: vinoyang
> Priority: Blocker
> Labels: flip6
> Fix For: 1.5.0, 1.6.0
>
>
> This only happens in flip6 mode. The {{CheckpointConfigHandler}} returns the
> checkpoint mode uppercased. For example:
> {code}
> {"mode":"EXACTLY_ONCE","interval":5000,"timeout":600000,"min_pause":0,"max_concurrent":1,"externalization":{"enabled":false,"delete_on_cancellation":true}}
> {code}
> However, the Web UI expects the value to be lower cased:
> {code}
> <tr>
> <td>Checkpointing Mode</td>
> <td ng-if="checkpointConfig['mode'] == 'exactly_once'">Exactly
> Once</td>
> <td ng-if="checkpointConfig['mode'] != 'exactly_once'">At Least
> Once</td>
> </tr>
> {code}
