i installed HDP 2.5 on a cluster composed by 2 nodes through Ambari Server. Now, I want to install NiFi through Amabari Server Web Interface -> Actions -> Apache NiFi. But this not is the right mode to install it.
How install I it?
HDF 2.0 introduced support for integration and installation via Ambari. HDF 2.0 requires its own Ambari to deploy and manage the HDF stack. You cannot install NiFi via HDP's stack/Ambari. Both products (HDP and HDF) are separate installs managed by separate Ambari installs.
Follow this exactly.
You cannot have Apache NiFi or Ambari or anything else on that machine before hand other than Python, Java 8 and the normal libraries. No existing HDP or HDF or NiFi installs.
Did you mean "cannot" instead of "can"?
The documentation at the link you provided states:
"Hortonworks Data Platform (HDP) and any of its components are not anticipated to be combined with any hardware, software or data, except as expressly recommended in this documentation."
sorry about, yes I meant cannot. I fixed that typo. I tried it and you can't have two different clusters managed by one ambari. So don't even try.
Try install Nifi using command line.
wget 'https://archive.apache.org/dist/nifi/1.1.1/nifi-1.1.1-bin.zip' unzip nifi-1.1.1-bin.zip sudo sh nifi-1.1.1/bin/nifi.sh start *Create a tunnel for your localhost:8080 *Access the URL: localhost:8080/nifi If you need change the default port, access the file sudo vi nifi-1.1.1/conf/nifi.properties And change de value 8080 For restart nifi sudo sh nifi-1.1.1/bin/nifi.sh restart Thanks!
