Everytime I try to restart clean restart fails but nifi but nifi will be running. Also tried restarting from cli same issue. Because of this I am unable to apply any conf changes from Ambari. Attached screenshot of the exception. It reads as stderr: Traceback (most recent call last): File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 982, in restart self.status(env) File "/var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/scripts/nifi.py", line 156, in status check_process_status(status_params.nifi_node_pid_file) File "/usr/lib/ambari-agent/lib/resource_management/libraries/functions/check_process_status.py", line 43, in check_process_status raise ComponentIsNotRunning() ComponentIsNotRunning The above exception was the cause of the following exception: Traceback (most recent call last): File "/var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/scripts/nifi.py", line 278, in Master().execute() File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 353, in execute method(env) File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 993, in restart self.start(env, upgrade_type=upgrade_type) File "/var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/scripts/nifi.py", line 152, in start nifi_cli.create_or_update_reg_client(params.nifi_registry_host, params.nifi_registry_url) File "/var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/scripts/nifi_cli.py", line 175, in create_or_update_reg_client existing_clients = list_reg_clients() File "/var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/scripts/nifi_cli.py", line 144, in list_reg_clients outputType="json" File "/var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/scripts/nifi_cli.py", line 73, in nifi_cli raise Fail("Failed to execute nifi cli.sh command") resource_management.core.exceptions.Fail: Failed to execute nifi cli.sh command Tried increasing heap settings, cleaning up logs.
