Are intermittent failures to restore from a SP, in the case of flink offset a know issue ? I had more than one instance where the offsets were not restored, but a retry ( in one case I it succeeded like the 4th restore attempt ) . I am on 1.3.2.
AFAIK, intermittent restore failures from savepoints should not be expected.
Do you still have the logs from the failed restore attempts? What exceptions
were the restores failing on?
We would need to take a look at the logs to figure what may be going on.
