You can use RounteOnAttribute if you have some way to identifying which files goes to which destination like in filename, path etc. Check attributes of the flow file to see if any can be used. Then use those attributes to create 3 paths, something like: https://community.hortonworks.com/questions/54811/redirecting-flow-based-on-certain-condition-nifi.html ... View more

A "multi node HDP cluster in Azure VM" can be created using normal Ambari managed HDP installation guide, this is not much different from setting a cluster on on-premise hardware or VMs on your desktop: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.5/bk_ambari-installation/content/ch_Getting_Ready.html Prerequisite will be to set up Azure VMs with storage and networking. You only need to pay Hortonworks for support, if needed. ... View more

As mentioned before, make sure your Hive Service is connected to the new location of MySQL. Removing MySQL without will result in losing all you metadata. You can use Ambari REST API to remove services manually: curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http: //AMBARI_SERVER_HOST:8080/api/v1/clusters/c1/services/SERVICENAME https://cwiki.apache.org/confluence/display/AMBARI/Using+APIs+to+delete+a+service+or+all+host+components+on+a+host ...

Pierre solution is correct. If you installed Atlas after Ranger UserSync has been configured to use LDAP, new local users will not get synced in ranger like atlas. This user is needed to setup hbase tables. To fix, revert UserSync to UNIX, restart only Ranger UserSync, Switch back to UserSync LDAP config. In Ranger add user atlas to HBase all policy. Restart Atlas. ... View more

Usually by default the ticket expires 24 hours and cache expires 7 days. Depends on your directory services policies. Within 7 days you can do kinit -R for users. klist will show ticket and cache expiry time. Or you can use keytabs to automate ticket renewal. You don't have to kinit for hadoop services (ever), ticket renewal is managed automatically. ... View more

We usually use Nifi Content and Provenance repository to troubleshoot failed flow files. Both are set to 7 days of retention. Plus you can replay content to debug. From zero API reporting perspective you can use row counts as attributes collecting total rows, success rows, failed rows etc. Depending on format of your source file this can be as simple as executing wc -l. Later converting these attributes to JSON and use MergeContent, Schema registry and query record to create an email report. ... View more
