@Ed Gleeck Please see this doc https://zookeeper.apache.org/doc/trunk/zookeeperAdmin.html#sc_zkMulitServerSetup I would deploy 2 in master and 1 in slave as you have only 2 master nodes. I highly recommend to increase the node count and have minimum 4 or 5 master servers for to distribute the master components and keeping the option open for HA.

Is it possible to integrate HDFS encryption with 3rd party KMS solutions? for example: Microsoft KMS I do see that there is Ranger KMS https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.4/bk_Ranger_KMS_Admin_Guide/content/ch_ranger_kms_overview.html but we are looking into the option to integrate HDFS encryption with the existing KMS.

@michael klybor You can access resource manager UI to see existing jobs running. or yarn application -list yarn application -kill appid --> apps dont' need then try running hive cli PS: Start using beeline instead of hive cli because of security reasons. Permanent solution is to enable yarn queues. https://community.hortonworks.com/articles/10912/yarn-queues-and-cs-view-queue-mapping.html

I am able to access gs without having kerberos ticket. I am guessing that it's normal but it would be nice to have a way to enforce kerberos auth for gs while accessing the GS from Hadoop. bash-4.1$ id

bash-4.1$ kdestroy

@oumayma ajengui See this demo https://community.hortonworks.com/articles/7819/apache-zeppelin-hive-spark-demo.html You will have to write your process to make it work for your usecase but above demo can be a good starting point.

@Marco Gaido I think you should try with zlib to test it out.
