[jira] [Created] (NIFI-8235) UnsupportedOperationException during PutAccumuloRecord validation

Zsihovszki Krisztina created NIFI-8235:
------------------------------------------

             Summary: UnsupportedOperationException during PutAccumuloRecord validation
                 Key: NIFI-8235
                 URL: https://issues.apache.org/jira/browse/NIFI-8235
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
    Affects Versions: 1.11.4, 1.11.3, 1.11.2, 1.11.1, 1.11.0
            Reporter: Zsihovszki Krisztina

In case "Column Family" and "Column Family Field" properties are not set properly on PutAccumuloRecord,  a bulletin error is reported with this message: "Failed to perform validation due to java.lang.UnsupportedOperationException". No error is logged in nifi logs.

Remote debugging revealed that the exception is thrown from PutAccumuloRecord.customValidate method.

[https://github.com/apache/nifi/blob/f9ae3bb9c970cd8d6d1d9e10f07cab9bdb66baa9/nifi-nar-bundles/nifi-accumulo-bundle/nifi-accumulo-processors/src/main/java/org/apache/nifi/accumulo/processors/PutAccumuloRecord.java#L268]

The method tries to add value to an immutable Collections.emptySet(), this is why the UnsupportedOperationException is thrown and the validation error is not reported properly.
