Query not Showing in the Nifi Twitter Demo

SQLShaw — Tue, 21 Apr 2026 12:32:26 GMT

I've successfully setup the Nifi Twitter demo before but recently started from scratch using the HDP 2.4 sandbox. Twitter data is coming in and persisting to HDFS. I've setup the Banana dashboard but I never see any data. What I'm noticing is when I navigate to http://sandbox.hortonworks.com:8983/solr/#/tweets_shard1_replica1/query there is no query displayed.

Any suggestions on how to get the query to install? I've ran all the steps without any errors and have restarted HDP Search. Navigating to http://sandbox.hortonworks.com:8983/solr/tweets_shard1_replica1/select?q=*:* gives me this:

I found the problem. I must have missed the step "chown -R solr:solr /opt/lucidworks-hdpsearch/solr". Once I did this the query worked but still did not see tweets in the dashboard. I deleted the collection and reloaded it. After that data started to appear.
