I'm trying to run a Flink 1.17.1 job with local execution through PyCharm.
My code is using the DataStream API and I'm reading data from a Kafka topic and printing it to the console with .execute().print().
However, I'm encountering some errors when using the slot_sharing_group, if I comment out the lines using slot_sharing_group.
I've checked that I have enough taskamanger.numberOfTaskSlots. (It would expect to see another error when I don't have enough task slots but I validated that number nonetheless).
Here's the error I'm getting:
py4j.protocol.Py4JJavaError: An error occurred while calling o545.print.

Any clue what could be the source of the exception ?
The problem was that I was setting my configuration at the Table API level while it should have been at the global configuration level.
So instead of this:
config = Configuration()
ds_env = StreamExecutionEnvironment.get_execution_environment(config)
t_env = StreamTableEnvironment.create(ds_env)
# Configuration at the Table API scope
t_env.get_config().set('parallelism.default', 1)
t_env.get_config().set('taskmanager.numberOfTaskSlots', 2)
I used this:
# Configuration at the global scope
config = Configuration()
config.set_integer('parallelism.default', 1)
config.set_integer('taskmanager.numberOfTaskSlots', 2)
ds_env = StreamExecutionEnvironment.get_execution_environment(config)
t_env = StreamTableEnvironment.create(ds_env)
And it worked.
