It seems to be coming since this change
[FLINK-13818|(https://issues.apache.org/jira/browse/FLINK-13818) ] :
[https://github.com/apache/flink/pull/9883]
The issue is that for history server we are not setting the web-submit feature
in the conf and the /config endpoint returns
{code:java}
{"refresh-interval":10000,"timezone-offset":-18000000,"timezone-name":"Eastern
Time","flink-version":"<unknown>","flink-revision":"d9f8abb @ 04.12.2019 @
16:16:24 EST"}{code}
while as in the Jobmanager the /config endpoint returns
{code:java}
{"refresh-interval":3000,"timezone-name":"Coordinated Universal
Time","timezone-offset":0,"flink-version":"1.9-criteo-rc1-1573156762","flink-revision":"366237a
@ 07.11.2019 @ 20:00:32 UTC","features":{"web-submit":true}}
{code}
*AppComponent.ts* fails at this line because the feature web-submit is not
found in the config:
{code:java}
webSubmitEnabled = this.statusService.configuration.features['web-submit'];
{code}
This can be fixed in two ways:
# Add defensive check in the *AppComponent.ts*
{code:java}
webSubmitEnabled =
(this.statusService.configuration &&
this.statusService.configuration.features &&
this.statusService.configuration.features['web-submit']);{code}
# Add the features property in the config file that *HistoryServer.java*
generates.
