Hi All, I am trying to restart one of my kafka broker for stale configuration due to ranger configuration changes. However, one of the kafka broker is not coming up and is not throwing any error as well. I reverted back the ranger configuration but to no avail. The only error that i see is the below error in the ambari stderr output: Traceback (most recent call last): File "/var/lib/ambari-agent/cache/common-services/KAFKA/0.8.1/package/scripts/kafka_broker.py", line 129, in <module> KafkaBroker().execute() File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py", line 280, in execute method(env) File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py", line 685, in restart self.stop(env, upgrade_type=upgrade_type) File "/var/lib/ambari-agent/cache/common-services/KAFKA/0.8.1/package/scripts/kafka_broker.py", line 96, in stop import params File "/var/lib/ambari-agent/cache/common-services/KAFKA/0.8.1/package/scripts/params.py", line 181, in <module> enable_ranger_kafka = not is_empty(enable_ranger_kafka) and enable_ranger_kafka.lower() == 'yes' AttributeError: 'bool' object has no attribute 'lower' ...
