@Vance Wei Try using Gremlin Server, this should give you access the the Titan layer and the ability to affect the underlying BerkeleyDB store. http://s3.thinkaurelius.com/docs/titan/0.9.0-M1/server.html

I run into the same problem, where the Ambari says it's installed, but the sqoop directory is not there on the data nodes. I am running in a cluster, but it should be the same for sandbox. The current answer does not address this, but the only way to fix this is to uninstall the sqoop client, and re-install it with Ambari. Unfortunately, current web UI does not allow uninstall of clients. Fortunately, you can do it through API calls. Command Syntax is follows: URL=https://${AMBARI_HOST}/api/v1/clusters/${CLUSTER_NAME}/hosts/${HOST_FQDN}/host_components/SQOOP curl -k -u admin:admin -H "X-Requested-By:ambari" -i -X DELETE $URL After that, you can re-install the sqoop client from the Web UI.

Vance currently in NiFi any user with the DFM permission can create as many flows as necessary. It is not uncommon for a single instance of NiFi to be handling hundreds or more processors representing what can be dozens or hundreds of distinct dataflows. It is also quite common for people to be surprised by that however a lot of effort has gone into the design of the repositories, threading model, and user interface to allow it to support a wide variety of functions and flows. It is certainly a solid compliment to the powerful analysis and processing platforms that systems like Storm and Spark provide or the storage/access systems that Kafka and HDFS provide.

Today I spoke with Robert Molina from Hortonworks and possibly found what is creating all those alerts! The sandbox is intended to be run on a desktop with a NAT networked interface. I set it up on a dedicaded headless server with a bridge adaptor. Looks like sandbox have a problem with that and that cause some of the services configs to not function properly! As a result some services works but reports network connections alerts! After some config change. The related alerts weren't there anymore. So always use a vm for and how it was intended to be used. Thanks to the hortonworks team and Robert who wanted to go to the bottom of this. Conclusion: If you want, like me, to test drive hortonworks on a headless server. Start from scratch and build it! What every sysadmin should do anyways... That's what I'll do this week end... P
