Hi @Brian Andrus I'm following up internally about the link not working. In the meantime, a slightly older version is working that might get you going again: http://public-repo-1.hortonworks.com/HDP/tools/2.6.0.3/hdp_manual_install_rpm_helper_files-2.6.0.3.8.tar.gz

Hi @Brendan Smith I've sent an internal inquiry to follow up on this. I'll post back here once I hear back. In the mean time, this one should work: http://public-repo-1.hortonworks.com/HDP/tools/2.6.0.3/hdp_manual_install_rpm_helper_files-2.6.0.3.8.tar.gz

Hi @Pingping Shang Ambari Infra is a specialized deployment meant for internal consumption for Ambari. The recommended approach would be to use HDP Search if you want to index your own data.

Hi @Sanaz Janbakhsh You could probably achieve that by combining processors. Use the Tika-based processor to extract everything from the pdf in txt form, and then use another processor (ExtractText with RegEx to find your content for example) to extract the specific text you want, and decide what to do with that content from there.

@John T apart from using FIFO priorotizization config on all of your connections, have you looked at the EnforceOrder processor in the latest version of NiFi? I think it does what you want? https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.3.0/org.apache.nifi.processors.standard.EnforceOrder/index.html

Hi @Shota Akhalaia Most of the deployments I have been involved with has seen these services be installed on bare metal machines also as a lot of organizations tend to do HDP and HDF together, but, I think these should be ok to virtualize as well.

hi @Shota Akhalaia The master services for the various tech are not usually overly IO heavy, and therefore, can be virtualized (and backed by SAN) without too much of an issue, including the NN but also the master services for the other technologies within the platform. Keeping the worker nodes on physical can help you to maximize your cluster's performance.

Hi @Sanaz Janbakhsh I just did a quick test using GetFile to ingest a PDF, and used the custom processor as is without any configuration. I then used a PutFile to drop the output of the Extracted text to a dir. As expected, the output is the text lifted from the original PDF, in a text file format. No special configuration required. If you are looking to play with the metadata using Tika, you can look at the ExtractMediaMetadata processor which comes with modern versions of NiFi out of the box and uses Tika under the hood.

Hi @John Koop I saw the screenshots, screenshot #1 looks good. Once you are there, can you access Ambari on http://127.0.0.1:8080 ? If so, you can start the tutorials, the welcome page on port 8888 is not really mandatory.

Hi @John Koop On your local laptop, you can use a text editor add an entry to your hosts file (/etc/hosts if you are using a *nix or Mac machine) that looks like the following: 127.0.0.1 sandbox.hortonworks.com sandbox
This allows your local laptop/PC to resolve "sandbox.hortonworks.com" in a browser to the IP address for your local host of 127.0.0.1. When you import the appliance to VirtualBox, you can start the VM and as you have already noted, boot into the third option for Linux OS's to start the Hortonworks Sandbox Software. When the software boots, you should see a screen that advises you to go to the start page of http://127.0.0.1:8888 or http://sandbox.hortonworks.com:8888 This start page contains some introduction material, as well as links to other areas like Ambari (http://sandbox.hortonworks.com:8080). You should be able to follow the tutorial once you are booted into the corrected OS (third one), and able to bring the screens in a browser.
