If they are enabled or running then it can cause tremendous slowdowns in response time by a multiple of 2-10x. This in turn leads the UI to be unresponsive. > Stacktraces such as this one are commonly present: > {quote} > "Clustering Tasks Thread-3" Id=172 BLOCKED on java.lang.Class@600aa5f8 > at org.apache.nifi.hadoop.SecurityUtil.isSecurityEnabled(SecurityUtil.java:83) > at org.apache.nifi.hadoop.KerberosProperties.validatePrincipalAndKeytab(KerberosProperties.java:121) > at org.apache.nifi.processors.hadoop.AbstractHadoopProcessor.customValidate(AbstractHadoopProcessor.java:154) > at org.apache.nifi.components.AbstractConfigurableComponent.validate(AbstractConfigurableComponent.java:123) > at org.apache.nifi.controller.StandardProcessorNode.isValid(StandardProcessorNode.java:912) > at org.apache.nifi.controller.FlowController.getProcessorStatus(FlowController.java:2529) > at org.apache.nifi.controller.FlowController.getGroupStatus(FlowController.java:2146) > at org.apache.nifi.controller.FlowController.getGroupStatus(FlowController.java:2162) > {quote} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
