Hi all,

I'm running in a strange effect, i've running a listHDFS processor with this config keytab and principal :

My user is "ute"

ute.keytab 
ute@FTI.NET

but i've got this message error :

nifi-app_2017-03-13_15.0.log:2017-03-13 15:59:59,670 ERROR [Timer-Driven Process Thread-8] o.apache.nifi.processors.hadoop.ListHDFS ListHDFS[id=93843bce-d367-108a-953c-19690d75dccf] Failed to perform listing of HDFS due to org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: polis@PSA.NET is not allowed to impersonate ute@PSA.NET: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: polis@PSA.NET is not allowed to impersonate ute@PSA.NET
nifi-app_2017-03-13_15.0.log:org.apache.hadoop.ipc.RemoteException: User: polis@PSA.NET is not allowed to impersonate ute@PSA.NET

Why my processor try to use another user in my case (polis) user ?

Thanks
