Got it syncing to the hub! So if i understand this correct, now if I want to sync these notebooks to another zeppelin, i just put in the same "hub_api_token" in that zeppelin and will it sync to that zeppelin instance? Or is that a feature that's not developed yet? ... View more

Hi, I will kerberize my cluster and then install Ranger. I will connect to Active Directory. As far as I understand, SSSD is deprecated since Windows Server 2012 R2 so, defining lookup on core-site.xml file seems to be the best way out. Is that correct? However, this change is made on core-site.xml file of HDFS only. How does other applications use the same lookup? Is HDFS the only level where user authorisation must be checked? Does let's say Hive or HBase, start process with authenticated user then leave the authorization to HDFS? How does it work? In the blog, some other user commented that we must import the cert from the KDC into the default JDK keystore for LDAP. keytool -importcert -file rootCA.pem -alias kdc -keystore /usr/java/jdk1.8.0_73/jre/lib/security/cacerts Is this manual step required for Kerberos, AD integrated clusters? Thanks in advance... ... View more
