Hi Fabian,
your hint was good! Maven fools me with the dependency management. Now
everything works as expected!
Many many thanks to all of you!

Hi Dominique,
can you check if the versions of the remotely running job manager &
task managers are the same as the Flink version that is used to submit
the job? The version and commit hash are logged at the top of the JM
and TM log files.
Right now, the local client optimizes the job, chooses the execution
strategies, and sends the plan to the remote JobManager. Recently, we
added and removed some strategies. So it might be that the strategy
enum of client and jobmanager got out of sync.
Cheers, Fabian

Hi,
glad you could resolve the POJO issue, but the new error doesn't
look right.
The CO_GROUP_RAW strategy should only be used for programs that
are implemented against the Python DataSet API.
I guess that's not the case since all code snippets were Java so
far.
Can you post the full stacktrace of the exception?

Hi all,
i finally figured out that there is a getter for a boolean
field which may be the source of the trouble. It seems that
getBooleanField (as we use it) is not the best choice. Now
the plan is executed with another error code. :(
Caused by: java.lang.Exception: Unsupported driver strategy
for join driver: CO_GROUP_RAW
Is there any link to a documentation or some example code
which you may recommend beside the offical documentation?
But folks, thanks for your greate support! A really nice
community here!

I tested the |TypeExtractor| with your |SourceA| and
|SourceB| types (adding proper setters and getters) and it
correctly returned a |PojoType|. Thus, I would suspect that
you haven’t specified the proper setters and getters in your
implementation.

Could you post the complete example code (Flink job
including the type definitions). For example, if the
data sets are of type |DataSet<Parent>|, then it will
be treated as a |GenericType|. Judging from your pseudo
code, it looks fine on the first glance.

Could you share the code for your types |SourceA|
and |SourceB|. It seems as if Flink does not
recognize them to be POJOs because he assigned
them the |GenericType| type. Either there is
something wrong with the type extractor or your
implementation does not fulfil the requirements
for POJOs, as indicated by Chiwan.

Oh, the fields in SourceA have public
