generally working now. except that every time it runs, it returns one and exactly one result .json file. i find it hard to believe that there is exactly one tweet meeting my criteria ever 30 seconds.

I've just finished reading up on twitter's API and perhaps rate-limiting is the issue. I'm using a template pulled from HWX and it looks like it had the scheduling set to zero seconds. I have increased it to 30 seconds and still it does not work. Will reset my keys and see if that fixes it. perhaps twitter cuts off access for those identifiers. What is a "reasonable" schedule time that won't run into the rate limit? Here are some log messages: 2016-07-27 05:38:49,352 INFO [hosebird-client-io-thread-0] com.twitter.hbc.httpclient.ClientBase GetTwitter[id=b2e83358-2e38-42c5-88a7-9f8a3f8307ba] Establishing a connection 2016-07-27 05:38:50,837 WARN [hosebird-client-io-thread-0] com.twitter.hbc.httpclient.ClientBase GetTwitter[id=b2e83358-2e38-42c5-88a7-9f8a3f8307ba] Error connecting w/ status code - 420, reason - Enhance Your Calm 2016-07-27 05:39:07,949 ERROR [Timer-Driven Process Thread-2] o.a.nifi.processors.twitter.GetTwitter GetTwitter[id=b2e83358-2e38-42c5-88a7-9f8a3f8307ba] Received error HTTP_ERROR: HTTP/1.1 420 Enhance Your Calm.

Get Twitter is working some but not all times. If I connect to the sample endpoint, it retrieves data. If I connect to the filter endpoint with a valid filter that contains popular topics, it retrieves nothing. If I go back to the sample endpoint, it eventually stops getting any data. If I regenerate my twitter keys, it seems to work for a while and then stops getting data. I saw the issue regarding server clock synchronization and I have made sure that nntp is running properly and the clock is right. not sure what else to adjust.

The tutorial says to use "now(0,0)" as the instance times, this is rejected with exception "start instance is before start of feed". What does "now(0,0)" mean, and what would be the proper value use? I suspect this is some kind of time relative to the current time. I searched for help on what "now(0,0)" means and didn't find anything.

solved it. the problem is introduced by copy/paste text from the tutorial page. it must introduce some garbage characters. someone else noted this as a problem with starting one of the other interpreters.

What browser are you using? I've had this same problem and it seemed to be caused by Ambari + IE 11 compatibility issues. I switched over to chrome and it worked fine.
