Andrey Zagrebin commented on FLINK-14360:
-----------------------------------------
[~shenyinjie] Could you explain a bit more what you are trying to do?
Looking into the PR, you are changing the part where this is up to Flink to
decide how to distribute the files which are basically local for the submitting
client.
Do you want to configure some other HDFS cluster(s) which Flink should use for
this purpose?
Do the file paths created in the current code not contain correct name nodes to
obtain necessary tokens or what is the problem?
> Flink on yarn should support obtain delegation tokens of multi hdfs namespaces
