Subject Re: Trouble migrating state from 1.6.3 to 1.7.1
Date Wed, 23 Jan 2019 17:38:05 GMT
Hi,

Thanks for reporting this.

Could you provide more details (error message, exception stack trace) that
you are getting?
This is unexpected, as the changes to flink-avro serializers in 1.7.x
should be backwards compatible.
More details on how the restore failed will be helpful here.

Cheers,
Gordon
