Hi All, We have developed NiFi flow which has one custom processor (lets call it CP) which uses custom controller service (lets call it CCS) which in turn uses NiFi's KeytabCredentialsService (lets call it KCS).
CP ==> CCS ==> KCS This flow is in processor group called development. We created template of this flow and gave it testing team. Testing team has imported this template in processor group called testing. Testing team has configured KCS with their own keytab. When testing team executes CP which is in testing processor group, they get access denied error. When we checked the processor, it showed the processor has used KCS of development processor group but in fact KCS configured is with testing key tab only. So we disabled KCS in testing processor group and enabled it again and it worked BUT then CP in development processor group gave same access denied error. In short, when processor in one processor group runs fine, processor in other processor group gets access denied error because it uses other keytab service. So we have to disable and enable processor group to resolve that error. Has anyone faced similar issue? Regards, Chandra
