Varun Vasudev updated HDFS-6904:
--------------------------------
Description:
YARN is unable to renew delegation tokens obtained via the WebHDFS REST API.
The scenario is as follows -
1. User creates a delegation token using the WebHDFS REST API
2. User passes this token to YARN as part of app submission(via the YARN REST
API)
3. When YARN tries to renew this delegation token, it fails because the token
service is pointing to the RPC port but the token kind is WebHDFS.
The exception is
{noformat}
