[jira] [Updated] (NIFI-15955) Possible NiFi 2.9.0 bug: groovyx ExecuteGroovyScript fails when Failure Strategy = "transfer to failure"
[ https://issues.apache.org/jira/browse/NIFI-15955?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Geoff Greene updated NIFI-15955:
--------------------------------
Description:
Subject:
Hi all,
We just upgraded to NiFi 2.9.0 and I believe we’ve identified a critical issue in the groovyx ExecuteGroovyScript processor.
Minimal reproduction:
Flow:
GenerateFlowFile -> ExecuteGroovyScript
simple ExecuteGroovyScript script:
def ff = session.get()
if (!ff) return
session.transfer(ff, REL_SUCCESS)
Behavior:
- If Failure Strategy = "rollback": works as expected
- If Failure Strategy = "transfer to failure": commit fails even though the script transfers to REL_SUCCESS
Even on the transfer to failure setting, the flow file remains in the incoming queue, and I get the bulletin:
ExecuteGroovyScript[id=4250f809-019e-1000-ba2b-dc7f5d729518] org.apache.nifi.processor.exception.FlowFileHandlingException:
... transfer relationship not specified. This FlowFile was not created in this session and was not transferred to any Relationship via ProcessSession.transfer()
Then a follow-on error:
ExecuteGroovyScript[id=4250f809-019e-1000-ba2b-dc7f5d729518] ... is not known in this session (StandardProcessSession[id=])
I'd really like to see a fix in 2.9.1
