Hi all!
I was trying to solve an issue regarding the slowing down of the provenance repository by switching to the volatile storage as documented in the documention and in various mailing list topics. However when I changed the configuration to: *nifi.provenance.repository.**implementation=org.apache.**nifi.provenance.* *VolatileProvenanceRepository* I received: *Caused by: java.lang.RuntimeException: Unable to create Provenance Repository* * at org.apache.nifi.controller.FlowController.<init>(FlowController.java:472)* * at org.apache.nifi.controller.FlowController.createClusteredInstance(FlowController.java:416)* * at org.apache.nifi.spring.FlowControllerFactoryBean.getObject(FlowControllerFactoryBean.java:61)* * at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:168)* * ... 41 common frames omitted* *Caused by: java.lang.RuntimeException: java.lang.IllegalStateException: The specified implementation class 'org.apache.nifi.provenance.VolatileProvenanceRepository ' is not known to this nifi.* * at org.apache.nifi.controller.FlowController.createProvenanceRepository(FlowController.java:869)* * at org.apache.nifi.controller.FlowController.<init>(FlowController.java:469)* * ... 44 common frames omitted* *Caused by: java.lang.IllegalStateException: The specified implementation class 'org.apache.nifi.provenance.VolatileProvenanceRepository ' is not known to this nifi.* * at org.apache.nifi.nar.NarThreadContextClassLoader.createInstance(NarThreadContextClassLoader.java:195)* * at org.apache.nifi.controller.FlowController.createProvenanceRepository(FlowController.java:867)* * ... 45 common frames omitted* I'm running the official 1.2 build. Thanks! Arnaud
