Hi Miki,
Sorry for the late reply. If you are able to reproduce the first problem, it
would be good to see the complete JobManager logs.
The second exception indicates that you have not removed all data from
ZooKeeper. On recovery, Flink looks up the locations of the submitted JobGraphs
in ZooKeeper. You can check for yourself which jobs will be recovered by
checking the contents of znode /flink/<namespace>/jobgraphs.
Best,
Gary
