Yang Wang commented on FLINK-21700:
-----------------------------------
I am trying to understand this issue.
[~zuston] do you mean Oozie will handle the security setting for HDFS and HBase
before Flink submission? And it could not be disabled. Right? Could you share
how Oozie set the tokens?
If this is case, then I think disabling fetching the delegation tokens for HDFS
/ HBase and leaving it to Oozie make sense to me.
