HTTPSource lets you ingest data into Solr by POSTing a file using HTTP. HTTPSource sends data using a channel to a sink, in this case a SolrSink. For more information, see Flume Solr BlobHandler Configuration Options.

1. Delete all existing documents in Solr:

   $ sudo /etc/init.d/flume-ng-agent stop
   $ solrctl collection --deletedocs collection3

2. Comment out TwitterSource in /etc/flume-ng/conf/flume.conf and uncomment HTTPSource:

   # comment out “agent.sources = twitterSrc”
   # uncomment “agent.sources = httpSrc”

3. Restart the Flume Agent:

   $ sudo /etc/init.d/flume-ng-agent restart

4. Send a file containing tweets to the HTTPSource:

   $ curl --data-binary \
   @/usr/share/doc/search-0.1.4/examples/test-documents/sample-statuses-20120906-141433-medium.avro \
   'http://127.0.0.1:5140?resourceName=sample-statuses-20120906-141433-medium.avro' \
   --header 'Content-Type:application/octet-stream' --verbose

5. Check the log for status or errors:

   $ cat /var/log/flume-ng/flume.log 

Use the Cloudera Search GUI at http://localhost:8983/solr/collection3/select?q=*%3A*&wt=json&indent=true to verify that new tweets have been ingested into Solr, as expected.
