Github user jvwing commented on the issue: https://github.com/apache/nifi/pull/1775 @tequalsme thanks again for contributing this cool upgrade to PutCloudWatchMetric. First, a couple of nickpicks: * PropertyDescriptor `name` should be a data key, typically lowercase, like "minimum". The `displayName` property should have a human-readable name "Minimum". Although the names and displayNames might be very similar now, this helps provide flexibility for later changes. I realize we didn't follow that convention creating PutCloudWatchMetric, and your changes are following the pattern established in the file. In this case, we should be different. * I found a Checkstyle warning for "Unused import - java.util.Comparator" (for TestPutCloudWatchMetric) running `mvn clean install -Pcontrib-check`. The processor performed well under proper use. So I moved on to improper use. For the statistic set scenario, if I provided some but not all of Minimum, Maximum, Sum, and SampleCount, the processor did not raise a validation issue and later ran into a NullPointerException parsing a double from Minimum (in this case). How about a validation clause to make sure you specified something for all four? Other validations worked well. Help/docs look good. Code coverage from unit tests is great. Code quality looks very high.
