Subject Cannot restore from savepoint after adding a sink operator
Date Thu, 03 Aug 2017 22:44:05 GMT
Hi all! I added a S3 bucketing sink operator to my flink job and tried to
start it from a savepoint using --allowNonRestoreState option, and it's
showing me this error:

I found on Flink official document saying:

So I suppose the restoration should succeed even if the operator number
doesn't match. Can someone explain to me why this happens, and what's the
possible solution?

FYI, some specs:
Flink version: 1.2.1
Job parallelism: 10
S3 sink parallelism: 1
Job execution graph:
