Usage of EvaluateJsonPath

[Kayak28 <ka...@gmail.com>]

Hello, Nifi Community members:
I am very new to Nifi, and this is actually my first try to use Nifi.

I am using Nifi 1.10 now, and want to gather data from twitter and to
import them to Apache Solr(search engine).
I followed the guide
https://blogs.apache.org/nifi/entry/indexing_tweets_with_nifi_and
According to the guide, data flows are like below.
1. GetTwitter Processor
2. EvaluateJsonPath Processor if success
3. RounteOnAttribute Processor if matched
....

Even though EvaluateJsonPath Processor does not have any warning message,
when I run Nifi group, the data does not flow to EvaluateJsonPath
Processor. (the data seems queued between GetTwitter and EvaluateJsonPath
Processor)

What can be a cause of this problem?

Any clue will be very appreciated.

Sincerely,
Kaya Ota
