How to deploy processor to Hortonworks NiFi

Описание: How to deploy processor to Hortonworks NiFi

If you have nifi locally, just execute the restart command located in the bin folder.
As I have nifi on a docker container, I will need to run this command but also start the container again.
To access to the restart command, we need to start the cmd of the container using this command
docker exec -it docker_nifi_1 /bin/bash
Wait some minutes and then, start the container again and start nifi
Following this command:
docker start docker_nifi_1
Wait about 10 minutes to let container be started
As you can see, our processor is ready to be used on nifi
We are ready to test our processor,
for this purpose I will use sample data on this page:
https://community.tableau.com/doc/DOC...
I will copy that file to a local folder on docker container. the path I will use is /opt/nifi/data
This copy would be similar as
docker cp nifi-utils-nar-1.0.0.nar docker_nifi_1:/opt/nifi/nifi-1.8.0.3.3.1.0-10/lib/nifi-utils-nar-1.0.0.nar
Now lets create our data flow.
Fetch the file loaded, and transform to csv
For the propertoes of our processor, I Created 3 props:
Sheet Index: You need to specify the index of sheet where the data is located
Skip rows: This property is also required. The default value in -1, means that no rows will be skipped. In our file, the first row is the header and we don't
want to import that row, so I put 1 row to skip.
Take rows: Number of rows to be transformed. If you want to transform all the rows in the worksheet, just put -1
As you can see, the data is parsed to csv
That's all
