Summary: Add a Validator for the PutCloudWatchMetric Processor's
Unit Parameter
Key: NIFI-9817
URL: https://issues.apache.org/jira/browse/NIFI-9817
Project: Apache NiFi
Issue Type: Bug
Components: Core UI
Affects Versions: 1.15.3
Environment: ProductName: macOS
ProductVersion: 12.2.1
BuildVersion: 21D62
Reporter: Pat Alwell
Assignee: Pat Alwell

The AWS PutCloudWatchMetric processor has a Unit property that requires a value
from AWS's CloudWatch API specifications. This value is a constant from a
predefined set of string parameters. The API enforces casing so a unit value of
"bytes" fails to make a successful API request, whereas "Bytes" succeeds. I've
attached a screenshot that leads to a stack trace.
The proposed fix includes a new Validator() to warn the user about the issues
prior to starting the PutCloudWatchMetric processor and a set to determine the
partitions for the Unit field in API requests to AWS.
