Peter Turcsanyi resolved NIFI-11342. ------------------------------------ Fix Version/s: 2.0.0 1.22.0 Resolution: Fixed > HDFS processors fail to get ClassloaderIsolationKey at startup > -------------------------------------------------------------- > > Key: NIFI-11342 > URL: https://issues.apache.org/jira/browse/NIFI-11342 > Project: Apache NiFi > Issue Type: Bug > Reporter: Mark Bathori > Assignee: Mark Bathori > Priority: Major > Fix For: 2.0.0, 1.22.0 > > Time Spent: 40m > Remaining Estimate: 0h > > At the start of NiFi, the HDFS processors fail to get ClassloaderIsolationKey > when only KerberosUserService is provided. The processor tries the get the > isolation key by calling the createKerberosUser method on the service but it > fails because at the time of method call the controller service is in > Disabled state. > https://github.com/apache/nifi/blob/main/nifi-nar-bundles/nifi-extension-utils/nifi-hadoop-utils/src/main/java/org/apache/nifi/processors/hadoop/AbstractHadoopProcessor.java#L224 > Error message: > {code:java} > Failed to determine ClassLoader Isolation Key for > PutHDFS[id=192e8080-0187-1000-ee4f-a7100d9d7dbb]. This could result in > unexpected behavior by this processor.: > org.apache.nifi.controller.service.ControllerServiceDisabledException: Cannot > invoke method public abstract org.apache.nifi.security.krb.KerberosUser > org.apache.nifi.kerberos.KerberosUserService.createKerberosUser() on > Controller Service with identifier 0e84e32e-0187-1000-5e37-8cd7279916f6 > because the Controller Service's State is currently DISABLED{code} > The problem only occurs after NiFi restart. Adding a new HDFS processor to > the canvas and setting the Kerberos UserService can properly get the > isolation key. -- This message was sent by Atlassian Jira (v8.20.10#820010)
