Every time i try to use the Hadoop Resource Manager web interface (http://resource-manger.host:8088/cluster/) i show up logged in as dr.who. My question, how can I login as another user? In this case i want to login as myself and have a higher lever of privileges than dr.who.
My Cluster is non kerberised.
Currently in hadoop only simple authentication and kerberos (SPNEGO) authentication is supported out of the box. So your requirement is not supported. Refer http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/HttpAuthentication.html
If the cluster is managed by Ambari, this should be added in Ambari > HDFS > Configurations>Advanced core-site > Add Property
Please let me know if that worked
What is Simple Athentication here: http://rm-host:8088/cluster?user.name=asif not asking password. and RM UI should show only jobs belong to Asif. but both are not happening, How can I achieve these, can I check LDAP credentials with Simple Authentication?
