You can find an example on how to write to an HBase kerberised cluster at the following URL. https://community.hortonworks.com/articles/1452/sa...

It looks like your application doesn't know how to get a kerberos ticket. You need to configure the krb5.conf on the Linux server that you are running from.

The usage for SSD that you've described do make sense ( spill, temp files, ... ) for SSD. We've also seen a good performance benefit in using them for zookeeper disks. IMHO, it will be better to use the SSD budget and invest it into additional servers. Having said that, I know few customers which have decided to use SSD for their HBase clusters in order to get the best performance. The second part of your question is much easier to answer. HDFS is supporting tier storage which let you define different class of storages. You can find some further information on heterogeneous storage at : http://hortonworks.com/blog/heterogeneous-storages... http://www.ebaytechblog.com/2015/01/12/hdfs-storag... http://www.slideshare.net/Hadoop_Summit/reduce-sto...

Where can I find an audit trail of every changes done via Ambari ? I would like something similar to the configuration diff that we can do using the UI with the addition of the username. Eg Olivier has changed umask to 077 in hdfs-site on Monday 5th of December 2014 at 2:20:21.123 I've found /var/log/ambari-server/ambari-config-changes.log but it doesn't show the specific change which has happened. I understand that I've got the version and i can diff w/ the previous version but i was wondering if we were recording it somewhere else.

If you've missed a folder at install time, you can use the API to amend it post-install, First, you will need to stop the service. You can then use the configs.sh script to easily modify it. configs.sh is located in /var/lib/ambari-server/resources/scripts on your ambari server If you would like to change the zookeeper log dir. ./configs.sh set localhost <clustername> zookeeper-env zk_log_dir “/my/new/zookeeper/log/directory”

@Jonas Straub when you see this behaviour could you make sure to log a ticket with our support team. FYI, I've asked support to get the ZK issue in a ticket.

As part of my DR, I would like to have a way of replicating my oozie job into a DR cluster. Is there a good way of doing it ? I was thinking of having the workflow in version control systems ( git, subversion, ... ) and to push them into the DR oozie server when moving to DR. Unfortunately, it's not possible as it is consider a change and will require a change request ( lengthy internal process ). Is there a plan to do it with Falcon in the future ?
