Hi @Artem Ervits, @Neeraj Sabharwal just to give you an update on this: - yes, there was/is enough space in /usr and the dir /usr/hdp/2.2.5.2-2 has been created - due to time pressure I decided to start again from scratch with ambari 2.0.1 (the combination which I used for earlier clusters as well), right now it looks good, also that particular host is up as a worker node - to cleanup all the nodes I used the hostcleanup python script and some additional directory deletions (due to non-standard directories, e.g. for logs) I will do the Ambari upgrade later on. Thanks for all you efforts

I solved this problem after adding this property to core-site.xml. <configuration> <property> <name>hadoop.security.authentication</name> <value>kerberos</value> </property> </configuration>

Right now I was able to enable SSL in Ranger 0.6.0 downloaded from the Apache Foundation but not in Ranger 0.5.0 included in HDP 2.4.0. Hope in the next release Hortonworks will upgrade Ranger to 0.6.0.

In Ambari the Hiveserver2 is shown as "green", but there is an alert indicating problem with the Hiverserver2 process. This is due to a known bug in HDP2.2.3/2.2.4, that at Hive startup time no Kerberos ticket will be grabbed. To get rid of that alert, login to the Hiveserver node, become user hive and execute a "kinit -kt /etc/security/keytabs/hive.service.keytab hive/<hiveserver>@<REALM>" (if you keytab is in that default directory) to ensure the hive user got a valid Kerberos ticket. Afterwards you can restart Hiveserver in Ambari and the alert will disappear (Thanks to @dprichici for highlighting this) Regards, Gerd

Thanks @Neeraj Sabharwal You are not concerned about having different values for "Enable authorization" before enabling Ranger 😉 ?

Did you figure out why this happens though? Is @ a special character?
