Oct 16, 2018. Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. Some of the high-level capabilities and objectives of Apache NiFi include: Web-based user interface Seamless experience between design, control, feedback, and monitoring; Highly configurable. Now we are splitting into three concurrent paths. This shows the power of Apache NiFi. We will write to Kudu, HDFS and Kafka. For the results of our cold path (tempf ⇐60), we will write to a Kudu table. Kudu Masters: edge2ai-1.dim.local:7051 Table Name: impala::default.weatherkudu Record Reader: Infer Json Tree Reader Kudu Operation Type: UPSERT.
Recently have been working with Apache Nifi for one my IoT Project. I would like to write a post on how to Install Apache Nifi in Windows 7.
Pre-requisites:
Step 1: Download Apache Nifi 1.0 from here.
Step 2: Download the zip file the mirror site as recommended. It would be around 740 MB patiently download it.
Step 3: Extract the folder and I moved nifi-1.0.0 to a root drive for each of access through windows command console.
Step 4: Now go to the command prompt and navigate to the nifi-1.0.0 directory
Step 5: Navigate to the bin directory
Step 6: You will find run run-nifi.bat, execute run-nifi
Step 7: You will see something like the below:
Step 8: Now open your favourite browser and type localhost:9090, I have changed the port from 8080 to 9090 in nifi.properties file. If you want, you can change that as well.
Step 9: Now you can access to the menu to get to know the version of you are running on
Step 10: Happy data flows with Apache Nifi!!!
Apache NiFi is a popular data pipeline software that uses directed graphs for data routing. Using various processors available in NiFi you can design data pipeline and transform your data and can route it to various data streaming and storage tools.
One such example data pipeline in NiFi can tail your file on the system and we can send that file’s data to a Kafka topic. NiFi includes hundreds of processor which we can use to design our flow. NiFi presents us with one simple User Interface on which we can use a simple pick and drop functionality to draw our data pipelines.
In this tutorial, you will install Apache NiFi 1.11 on CentOS 7
Prerequisites

-m flag will ensure that useradd is creating home directory for nifi user
Step 2 — Increase Maximum File Handlers
As NiFi is IO-intensive application you will need to increase the open file handlers for nifi user. To increase that limit for nifi user we will edit file /etc/security/limits.conf and add below lines
Add below lines in the end of file limits.conf
Step 3 — Increase Maximum Forked Processes
NiFi uses a pool of thread to run processor running on Canvas. According to configuration, NiFi may need to run high number of threads on Linux system so you will need to increase the maximum allowable number by increasing /etc/security/limits.conf
Add below line at the end of file limits.conf

Step 6 — Start NiFi Server
