Jark Wu commented on FLINK-19912:
---------------------------------
Thanks for the investigation [~hailong wang]. I think it's not friendly to
throw exceptions during runtime in a long-running streaming job.
There are several options in my mind:
1) validate the map key type is not nullable, otherwise throws an exception
during compile phase (however, this may introduce a backward incompatible
problem, we may need to add a release note for this).
2) ignore entires with null key, and add a NOTE in JSON format docs.
What do you think about this [~hailong wang] [~twalthr] ?
