Hi @Felix Albani, The above issue is solved. Now we are facing strange thing, we have created a new user say snehal, created snehal@EXAMPLE.COM principal and snehal.keytab with this principal. And added "hadoop.proxyuser.snehal.groups=* , ,hadoop.proxyuser.snehal.hosts=* " properties in HDFS->config->custome-core site. same way added property for webhcat also. Now i am hitting > GET https://host:8443/gateway/default/webhdfs/v1/?op=GETHOMEDIRECTORY&user.name=snehal I am getting {"RemoteException":{"exception":"SecurityException","javaClassName":"java.lang.SecurityException","message":"Failed to obtain user group information: java.io.IOException: Usernames not matched: name=snehal != expected=knox"}}
Non activated Name node :https://host:8443/gateway/default, Error Message: 403#@_#{"RemoteException":{"exception":"SecurityException","javaClassName":"java.lang.SecurityException","message":"Failed to obtain user group information: java.io.IOException: Usernames not matched: name=snehal != expected=knox"}} Tried many ways like, adding the user snehal in supergroup, also did "kdestroy -> kinit with snehal keytab and principal" many times with different users also, Restarted ambari-server. But no luck. Thanks, Snehal
