------------------------------------
Summary: Yield in ExecuteScript when catching ScriptException
Key: NIFI-5437
URL: https://issues.apache.org/jira/browse/NIFI-5437
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Pierre Villard
Assignee: Pierre Villard
In case of ScriptException in ExecuteScript, a flow file can be processed again
and again which can lead to resource exhaustion and node instability.
Proposition: yield the processor when an exception is caught before throwing a
Process Exception.
Example of exception:
{code:java}
