             Summary: TextIO (and others) should provide more informative messages when encountering RVP
                 Key: BEAM-1289
                 URL: https://issues.apache.org/jira/browse/BEAM-1289
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-extensions
            Reporter: Ben Chambers
            Assignee: Davor Bonaci
            Priority: Minor


https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/TextIO.java#L301

When reporting failing to validate because a parameter comes from a RuntimeValueProvider (such as when creating templates) we report:

"Cannot validate with a RVP"

We should instead provide a message saying what went wrong and how to fix it. Something like:

"Unable to validate parameters that aren't available until runtime. Disable validation using .withoutValidation()."
