Does the job runs in detached mode or attached mode? Could you share some code
snippets and the job submission command if possible?

Dian,
Thanks for your reply. Yes, I would submit the same job in kubernetes
session mode. Sometimes the job would succeed but successive tries would
fail. No stack trace, the job would never return a job id:
In this case I redeployed the cluster and the job completed ... and
multiple tries were
Hi Robert,
1) Do you mean that when submitting the same job multiple times and it succeed
sometimes and hangs sometimes or it only hangs for some specific job?
2) Which deployment mode do you use?
3) Is it possible to dump the stack trace? It would help us understanding
what’s happening.
Thank
Thanks All,
I've added python and pyflink to the TM image which fixed the problem. Now
however submitting a python script to the cluster successfully is sporadic;
sometimes it completes but most of the time it just hangs. Not sure what
is causing this.

Hi,
>From the error message, I think the problem is no python interpreter on
your TaskManager machine. You need to install a python 3.5+ interpreter on
the TM machine, and this python environment needs to install pyflink (pip
install apache-flink). For details, you can refer to the document[1].

Okay, I added the jars and fixed that exception. However I have a new
exception that is harder to decipher:

Hey,
are you sure the class is in the lib/ folder of all machines / instances,
and you've restarted Flink after adding the files to lib/ ?

Shuiqiang,
I added the flink-connector-kafka_2-12 jar to the /opt/flink/lib directory
When submitting this job to my flink cluster I’m getting this stack trace
at runtime:
org.apache.flink.runtime.JobException: Recovery is suppressed by
NoRestartBackoffTimeStrategy
at
org.apache.flink.runti
Hi Robert,
You can refer to
https://github.com/apache/flink/blob/master/flink-end-to-end-tests/flink-python-test/python/datastream/data_stream_job.py
for the whole example.
Best,
Shuiqiang

Hi Robert,
Kafka Connector is provided in Python DataStream API since release-1.12.0.
And the documentation for it is lacking, we will make it up soon.
The following code shows how to apply KafkaConsumers and KafkaProducer:
```
env = StreamExecutionEnvironment.get_execution_environment()
env.set_
