Howdy guys, I have visibility of several webui's Ranger, Atlas and WebHDFS. The cluster is Kerberized and has HA on the NameNode (Ambari-2.4.2 + HDP-2.5.3) There is a firewall between knox and both the namenodes and my declaration. <gateway> ... <!-- required for HA --> <provider> <role>ha</role> <name>HaProvider</name> <enabled>true</enabled> <param name="WEBHDFS" value="maxFailoverAttempts=3;failoverSleep=1000;maxRetryAttempts=300;retrySleep=1000;enabled=true" /> </provider> </gateway> <service> <role>WEBHDFS</role> <url>http://ACTIVENN:50070/webhdfs</url> <url>http://STANDBYNN:50070/webhdfs</url> </service> <service> <role>HDFSUI</role> <url>http://ACTIVENN:50070</url> </service> <service> <role>NAMENODE</role> <url>hdfs://ha-name-for-cluster</url> </service> Note: The log page on the last tabs says "unauthorized dr.who 403" I noticed a similar problem here: https://issues.apache.org/jira/browse/KNOX-626 https://community.hortonworks.com/content/kbentry/67710/unable-to-access-datanode-tab-from-namenode-ui.html What are the reasons why there might be missing tab data? ...

Hello team, The documentation for KDC installation on HDP-2.5.3 includes instructions for SLES12 which suggests using: rckrb5kdc start rckadmind start chkconfig rckrb5kdc on chkconfig rckadmind on However, SLES 12.1 does not have the required rckrb5kdc.service or rckadmind.service files required to enable systemd to process the chkconfig commands above. It does however have kadmind.service and krb5kdc.service allowing me to run: chkconfig krb5kdc on chkconfig kadmind on However now I wonder if rckrb5kdc and rckadmind are now deprecated? Thoughts? ... View more

Hello team, I have a knox target that has JDBC connected to it. However although I'm happily connecting interactively, using command arguments for the url seem to be providing grief. I'm using Beeline 1.2.1000.2.5.3.0-37 could this be a bug?
