hi @Sonu Sahi, i've added nifi as a service in my HDP 2.6, but i'm having some difficulties to connect it to cassandra which is installed on my linux host. I'm wondering if i have to install cassandra in my sandbox too? Can you please take a look here for more details: https://community.hortonworks.com/questions/103622/how-to-use-querycassandra.html

Cassandra is running on my linux host, and nifi is installed as a service in my HDP sandbox.

Hello, I want to use the querycassandra processor, but i'm facing some troubles. I'm trying to do some very basic actions which is selecting all rows from a table and then send them to another ExcecuteStream processor(java program). Here is the table : Here is the processor configuration. I've also added the port 9042 to the HDP sandbox both from the port forwarding table and the start_sandbox script: username/password: cassandra a global schema showing the error: all host(s) tried for query failed (tried: /127.0.0.1:9042 (com.datastax.driver.core.exceptions.TransportException:[/127.0.0.1] Cannot connect)

thanks a lot! just one more question, how to get the output from the java program in nifi?

adib_elaraki · ‎05-16-2017

Can you please give me an example?

Hi everyone, i want to take some terms from a cassandra database, and then send them as a parameter to java program which will output some data that i will need to save in a cassandra database. Is this possible with nifi, if yes, which processors to use? specially for the execution of the java program, since i've seen that processors for cassandra already exists. Thanks!

Hello, i'm on the tutorial 'ANALYZE TRAFFIC PATTERNS WITH APACHE NIFI', unfortunately i'm having a problem, nifi can't access the repository where my data is. Here is the general schema: The error: (Getfile processor) The processor configuration. The directory on files view: versions: HDP 2.6 Nifi: nifi-1.1.0.2.1.2.0-10-bin (added as a service to hdp sandbox) Thanks !
