Hello. I have been going through the Analyzing Twitter Data With Apache NiFi and HDP Search tutorial using Sandbox VM I downloaded a couple of weeks ago.
I did run 'echo 127.0.0.1 sandbox.hortonworks.com >> /etc/hosts' (I am assuming the partial quotation marks in 'echo "127.0.0.1 sandbox.hortonworks.com >> /etc/hosts' in the instructions are a typo), and my /etc/hosts file now looks like this:
127.0.0.1 localhost.localdomain localhost 10.0.2.15 sandbox.hortonworks.com sandbox ambari.hortonworks.com 127.0.0.1 sandbox.hortonworks.com
However, the following links never work:
So, I replace 'http://sandbox.hortonworks.com' with '127.0.0.1' and NiFi and Solr seem to work fine, based on my limited understanding. However, when I get to starting Banana, and, go to '127.0.0.1:8983/solr/banana/index.html' (I am assuming that leaving out 'index.html' from 'http://sandbox.hortonworks.com:8983/solr/banana/' in the instructions is just an oversight, since without it we just see contents of the directory), I do get the basic Banana dashboard layout with black/gray background and buttons and rows and headers, but no data. I get the following two errors:
'Error Could not contact Solr at http://sandbox.hortonworks.com:8983/solr/. Please ensure that Solr is reachable from your system.' 'Error Could not retrieve collections from Solr (error status = 0)'
I thought, perhaps, if I replaced 'http://sandbox.hortonworks.com' with '127.0.0.1' in the 'default.json' file I downloaded from github earlier in the tutorial that might fix the problem, but Banana still saw no data, even though the error messages have changed slightly:
'Error Collection not found at 127.0.0.1:8983/solr/tweets. Please check your configuration or create the collection. If you are using a proxy ensure it is configured correctly.' 'Error Could not retrieve collections from Solr (error status = 404)'
The 'tweets' collection DOES exist, from what I can tell. If I enter the command we are given to create it, I am told it already exists. I can delete it and create it again, but that does not seem to make a difference for Banana.
Why does adding 'sandbox.hortonworks.com' to /etc/hosts not seem to work for me, does that mess anything else up besides Banana that I perhaps do not realize, and is there a workaround?
This may not have been specified but you should add "sandbox.hortonworks.com" to your HOST machine. This is not the sandbox. It is the machine which you have installed virtualbox/vmware on
On a windows machine you'll find your hosts file at
If you are using *nix system or Mac OS X it is simply
After editing the correct file on the host machine it should work
