@Zubair Jaleel There are many Kappa and other case studies presented at the DataWorks Summit (e.g. Ford, Yahoo, etc.). Videos and Slides are available for most sessions: https://dataworkssummit.com/san-jose-2017/agenda/

@Smart Data Ranger can be used to sync users with LDAP/AD. Credentials are stored in LDAP/AD, and Ranger configured to access. Knox is used as a proxy, but more for REST API service calls, and some UIs. It is not meant to proxy high volume traffic like Kafka messages.

@Smart Data Atlas is more Governance related, security to a less extent. You secure Kafka via Kerberos for authentication, and Ranger for authorization: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.1/index.html#bk_security

@Roberto Sancho This error can occur if you do not have adequate permissions on the file. I would suggest you run the 'fsck' command to determine if there are any corrupt blocks on HDFS. Is it only certain queries that fail, or all queries? Would also locate the under-lying files on HDFS, and check permissions, etc.

@Farrukh Munir The HA Guide covers this, and yes Ambari can be used to install, configure, and manage the services. https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.1/index.html#bk_hadoop-high-availability

@Qinglin Xia Checking you created the Tag Service in Ranger. You need to define the Tag Service to enable tags flowing from Atlas to Ranger. And always worth checking all the components are online - Ranger Tag-sync, Kafka, etc.

@ahmed bejaoui I would recommend: https://community.hortonworks.com/questions/103514/nifi-and-storm-withour-kafka.html and also to look at the Partner Demo Kit: https://community.hortonworks.com/articles/75341/partner-demo-kit-1.html which has a packaged demo of the IoT Trucking App - which includes Ni-Fi, Kafka, and Storm. All ready to go in a few easy steps.

@Vishal Gupta Would always advise to review the documentation on the Ambari and HDP upgrade. Generally, no, you don't need to re-gen all of the keytabs or SSL in the cluster as part of an upgrade - though Ambari will generate keytabs as required post-upgrade. https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.2.0/bk_ambari-upgrade/content/upgrading_HDP_post_upgrade_tasks_ranger_kerberos.html There are certain cases which need some attention (e.g. Kafka at 2.2, Ranger HA, etc.). https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/index.html You can raise a ticket with Hortonworks Support prior to the upgrade, as they can inform you on any known issues (if you have a subscription). Also, would recommend to move to 2.5.5 if moving to 2.5. And testing is imperative. Would advise to test all of the components under representative use cases.

@Christophe Vico I recommend you download the Sandbox: https://hortonworks.com/products/sandbox/ From Zeppelin, and in the one notebook, you can run different versions of Spark (1.6.3 or 2.1) as per your choice of interpreter: %spark.spark or %spark2.spark You can review the settings used in the Interpreter screen.
