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. ...

Thanks jwitt. I understand, but the parts are talking about supporting different levels of access within one flow for different users. What I am looking for is creating different flows for the same user or different users. Is the latter currently possible for Nifi? Or is having one flow per instance is the underlying basic assumption of Nifi? ... View more

I have found out how to resolve the "Connection failed on host sandbox.hortonworks.com" failures for my sandbox. The fix is to add sandbox.hortonworks.com to your no_proxy variable in /etc/profile. It turns out I receive this error because I am using sandbox behind corporate proxy, and have http_proxy and https_proxy setup. Even though sandbox.hortonworks.com is resolved to a local ip in the /etc/hosts file, that local ip is not always the localhost, but an IP in range 10.0.X.X if you are using NAT. Therefore, the request is hitting the proxy first, which resulted in a failure. ... View more

I have scanned all the java classes from the flume 1.5.2 lib, and I have two jars relating to kafka, the kafka-client-0.8.2-beta.jar and kafka_2.10-0.8.2-beta.jar. However, they don't seem to be for source and sink. The flume 1.6 contains classes for kafka source and sink explicitly. Therefore, I doubt the source and sink works with Flume 1.5.2 in HDP 2.3+. I am also looking into ways to get Flume to work with Kafka in HDP 2.3. If any of you have working examples, and can share your conf file, I would highly appreciate it. ... View more
