@tzulitai ï¼When I have fixed the problem, I want to write a IT case. But,
in the Yarn IT case:
1ã It uses the yarn mini cluster, which is for testing.I do not know
whether it is using HDFS Delegation token or not.
2ãAnd what's more, the HDFS Delegation Token is used by yarn node
manager. It is difficult to judge whether to have this token or not in yarn
client. The token is set into yarn application context,but the yarn client does
not have API to get yarn application context.
How do you think ? Thanks a lot!
