@Carter Everett and @luis marmolejo, the audit implementation has changed HDP 2.3 onwards. Previously the audits were written to local file and copied over to HDFS. From HDP 2.3 onwards, the audits are streamed directly to HDFS. It is written to the local spool folder only if the destination is not available.

@Ramesh Mani, do we have references to enable this via Ambari? If we manually modify the config file, it will be overwritten next time Ambari restarts Ranger. This is assuming Ambari is used to manage the cluster.

It would depend on which DB vendor you are using and what sort of license you have for your RDBMS. If you don't already have replication at the DB level, you might just for regular export of the DB, e.g mysqldump in MySQL would be a good short term solution for you

The best option is to just backup your Ranger database. For production, you should also consider setting up DB level replication (active/active or active/passive). This will give you HA and DR.

Don't forget to change the umask. Either 077 or 027

I generally add "-b ~/cookie.txt -c ~/cookie.txt" also the curl command. And "-i" will give addition information also. curl --negotiate -u : -b ~/cookie.txt -c ~/cookie.txt ...

Great article. One feedback while creating collections, instead of #shards=1, it should be &numShards=1 curl --negotiate -u :"http://horton04.example.com:8983/solr/admin/collections?action=CREATE&name=films&numShards=1"

@Benson Shih, what does the Audit say? It should have the policyId which gave permission.

When security is enabled, we should also set the HDFS umask to 077 or 027

Can you make sure that the password for amb_ranger_admin in RangerAdmin->User is the same as in Ambari -> Ranger -> Config -> Ambari Admin User
