I've setup Hadoop to use Kerberos (following the Cloudera security guide), but it is unclear how I connect to hadoop with regular users (e.g. username=myuser).
Currently I have myself authenticated with Kerberos with my Keberos
admin user (via kinit kerbadmin/admin
), but that doesn't seem to
help. Do I need to tell Hadoop that kerberos user "kerbadmin" is
allowed to use Hadoop?
Running something like hadoop fs -ls /
results in a permission
issue:
11/09/13 11:13:03 WARN ipc.Client: Exception encountered while connecting to the server : javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]

Also, sudo -u hdfs hadoop fs -ls /
returns the same error message.
