I got rid off SPNEGO on this cluster and set oozie.authentication.type=simple as I'm accessing from Mac, I don't need SPNEGO. I'm able to access Oozie UI now.

getting the following error on Oozie UI, cluster is kerborized, HDP 2.5.3, Ambari 2.5 (dev build): HTTP Status401- org.apache.hadoop.security.authentication.util.SignerException:Invalidsigned text:

I'll post this as separate question

@Predrag Minovic I changed the following properties oozie.service.ProxyUserService.proxyuser.ambari-server-mycluster.groups=* oozie.service.ProxyUserService.proxyuser.ambari-server-mycluster.hosts=* based on this jira https://issues.apache.org/jira/browse/FALCON-326 as I was getting error in oozie-error.log below /admin/configuration?doAs=admin] error, User [ambari-server-mycluster] not defined as proxyuser java.security.AccessControlException: User [ambari-server-mycluster] not defined as proxyuser at org.apache.oozie.service.ProxyUserService.validate(ProxyUserService.java:149) at org.apache.oozie.servlet.JsonRestServlet.getUser(JsonRestServlet.java:567) now I'm able to load workflow manager, which was my intended goal though I didn't specify in the question but my Oozie UI still doesn't load but error message changed to HTTP Status 401 - org.apache.hadoop.security.authentication.util.SignerException: Invalid signed text: this most likely has to do with all other properties I was messing with.

@Adnan Alvee that is impressive indeed, ORC has additional benefits you will see on the Hive side. Glad you found it of use.

Please use backtick for column name and it will treat all characters in the field literally Table names and column names are case insensitive. In Hive 0.12 and earlier, only alphanumeric and underscore characters are allowed in table and column names. In Hive 0.13 and later, column names can contain any Unicode character (see HIVE-6013). Any column name that is specified within backticks ( ` ) is treated literally. Within a backtick string, use double backticks ( `` ) to represent a backtick character. https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Select

When you enable HA, you essentially are changing name of the namenode with nameservers, you have to update hbase.rootdir property to reflect the nameservices ID and hence the stop. <property> <name>hbase.rootdir</name> <value>hdfs://namenode.example.org:8020/hbase</value> </property>

I would remove Ambari and agents, delete the whole directory /usr/lib/python2.6/site-packages/ambari* and try again

aervits · ‎03-08-2017

You can upgrade Ambari to 2.4.2 and then follow the standard upgrade process to upgrade HDP from 2.3 to 2.5.3.

Oozie UI is the only one I'm getting 401 on, I enabled SPNEGO and configured my browser (Firefox) to accept the domain. Still getting 401 error. Any suggestions, issue is similar to https://community.hortonworks.com/questions/25915/oozie-ui-is-not-accessible-in-kerberised-cluster-t.html
