@apiri @zenfenan FYI, I just manually pushed that commit. It was a one
liner on an approved commit, so didn't feel like it needed a review.
> Failed EL date parsing live-locks processors without a failure relationship
> ---------------------------------------------------------------------------
>
> Key: NIFI-5448
> URL: https://issues.apache.org/jira/browse/NIFI-5448
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: David Koster
> Assignee: Mike Thomsen
> Priority: Major
> Fix For: 1.8.0
>
>
> Processors that utilize the Expression Language need to always present a
> failure relationship.
> If a processor with only a success relationship, for example UpdateAttribute,
> utilizes the expression language to perform type coercion to a date and
> fails, the processor will be unable to dispose of the FlowFile and remain
> blocked indefinitely.
> Recreation flow:
> GenerateFlowFile -> Update Attribute #1 -> Update Attribute #2 -> Anything
> Update Attribute #1 - test = "Hello World"
> Update Attribute #2 - test = ${test:toDate('yyyy-MM-dd')}
>
> Generates an IllegalAttributeException on UpdateAttribute.
>
> The behavior should match numerical type coercion and silently skip the
> processing or offer failure relationships on processors supporting EL
