I am trying to run a mapreduce job on Hopsworks installed on 5 nodes according to the following configuration: 2 resource manager and 3 node manager. When the application is submitted to yarn, this generates 2 containers which are run on 2 separate node manager (eg NM1 and NM3). On the first node manager I can see the jwt token materialized correctly while on the other node manager no, and the job is in exception as reported below:
Caused by: org.apache.hadoop.ipc.RemoteException(java.io.IOException): JWT is enabled but it either null or empty for application application_1587625393033_0004
On the first node manager, this exception does not occur because the jwt token is correctly materialized.
Is it a bug? Or I am doing some configuration wrong?
The jwt token is enabled because the following configuration is a true one: yarn.resourcemanager.rmappsecurity.jwt.enabled
Thanks so much,
