Hi Guilherme, Ranger itself supports HA, meaning you can install multiple instances of the Ranger Admin UI. However as far as I know, Ranger does not support HDFS HA at the moment, so you need to set the active namenode in the repository setting of the HDFS service. This setting is only used for lookups when you create new Policies, so if you can live without this feature, its not a big deal. Jonas

Could you share some log and configurations? I'd be interested in the log that is produced when you open that view or press the refresh button of the database explorer

The HS2 instances register with ZooKeeper under a namespace. When a HiveServer2 instance comes up, it registers itself with ZooKeeper by adding a znode in Zookeeper. The znode name has the format: /<hiveserver2_namespace>/serverUri=<host:port>;version=<versionInfo>; sequence=<sequence_number> To de-register a single HiveServer2, enter hive --service hiveserver2 --deregister <package ID> You can find more information about HiverServer2 within Zookeeper on http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_hadoop-ha/content/ha-hs2-service-discovery.html

Hi Chakra, you can change the Anonymization configuration (Regex rules) via Ambari. Go to the Smartsense service and under "Config" there is a tab called "Data Capture" with all the necessary configurations. The documentation for Smartsense is available in the Support Portal, under Tools -> Documentation. This PDF contains information on how to upload analysis and support bundles as well as how to configure anonymization rules. Jonas

Hi @Olivier Renault could you dump the code into a Git repository, this way it is easier to copy and use the code. Thanks 😃

I have seen a similar issue a couple weeks ago. Ambari was running fine, but after some time I had to restart ambari-server because Ambari Metrics was spamming the ambari log. If you have Ambari Metrics installed and enabled, could you please stop the service, restart ambari server and see if the problem still occurs? Also make sure you Ambari Metrics Service is configured correctly, especially the heap (usually too low by default). Check this link for heap tuning https://cwiki.apache.org/confluence/display/AMBARI/Configurations+-+Tuning

Do you want to enable Knox High Availability (having multiple Knox instances) or do you want to enable HDFS HA within your Knox instance? If the latter, check out the WebHdfs HA section on https://knox.apache.org/books/knox-0-6-0/user-guide.html#WebHDFS To enable HA functionality for WebHDFS in Knox the following configuration has to be added to the topology file: <provider>
<role>ha</role>
<name>HaProvider</name>
<enabled>true</enabled>
<param>
<name>WEBHDFS</name>
<value>maxFailoverAttempts=3;failoverSleep=1000;maxRetryAttempts=300;retrySleep=1000;enabled=true</value>
</param>
</provider>
And for the service configuration itself the additional URLs that standby nodes should be added to the list. The active URL (at the time of configuration) should ideally be added to the top of the list. <service>
<role>WEBHDFS</role>
<url>http://{host1}:50070/webhdfs</url>
<url>http://{host2}:50070/webhdfs</url>
</service>
Let me know if that helps Jonas 😃

We already had some clusters going from HDP 2.1 directly to HDP 2.3.2 and apparently only minor issues along the way, nothing serious though.
