@wangrenlei Travis CI reported [RAT check
error](https://travis-ci.org/apache/nifi/jobs/212601713) as below:
```
[ERROR] Failed to execute goal org.apache.rat:apache-rat-plugin:0.11:check
(default-cli) on project nifi-web-ui: Too many files with unapproved license: 5
See RAT report in:
/home/travis/build/apache/nifi/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-web-ui/target/rat.txt
-> [Help 1]
```
I haven't checked out this PR yet, but suspect these RAT errors came from
newly added properties files (or other files). Because those don't have
appropriate license note in it. Please add Apache 2 License note at the head of
each files.
[nifi.properties](https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-resources/src/main/resources/conf/nifi.properties)
can be a reference for doing that.
Then please make sure mvn build passes with `contrib-check` profile as
written in the [Contributor
Guide](https://cwiki.apache.org/confluence/display/NIFI/Contributor+Guide#ContributorGuide-Providingcodeordocumentationcontributions):
```
