I am installing HDP2.4 with ambari2.4 and I am getting these "file not found " errors , if I create a directory manually the process moves ahead n fails on other directories. apparently ambari install is expecting ambari-agent to be installed already? if that's the case I have never done this step manually before . so what i am missing ? i have installed the cluster before by just installing ambari-server and initiating the install from web. ========================== Running setup agent script... ========================== Command start time 2017-06-16 17:41:00 /usr/sbin/ambari-agent: line 97: ambari-sudo.sh: command not found /usr/sbin/ambari-agent: line 99: ambari-sudo.sh: command not found /usr/sbin/ambari-agent: line 100: ambari-sudo.sh: command not found /usr/sbin/ambari-agent: line 101: ambari-sudo.sh: command not found /usr/sbin/ambari-agent: line 102: ambari-sudo.sh: command not found /usr/sbin/ambari-agent: line 103: ambari-sudo.sh: command not found /usr/sbin/ambari-agent: line 104: ambari-sudo.sh: command not found /usr/sbin/ambari-agent: line 105: ambari-sudo.sh: command not found ('INFO 2017-06-16 17:41:06,285 DataCleaner.py:39 - Data cleanup thread started INFO 2017-06-16 17:41:06,286 DataCleaner.py:120 - Data cleanup started INFO 2017-06-16 17:41:06,287 DataCleaner.py:122 - Data cleanup finished INFO 2017-06-16 17:41:06,328 PingPortListener.py:50 - Ping port listener started on port: 8670 INFO 2017-06-16 17:41:06,330 main.py:349 - Connecting to Ambari server at https://hadoop1.tolls.dot.state.fl.us:8440 (10.100.44.17) INFO 2017-06-16 17:41:06,330 NetUtil.py:65 - Connecting to https://hadoop1.tolls.dot.state.fl.us:8440/ca INFO 2017-06-16 17:41:06,389 main.py:359 - Connected to Ambari server hadoop1.tolls.dot.state.fl.us ERROR 2017-06-16 17:41:06,390 main.py:392 - Exiting with exception: Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/ambari_agent/main.py", line 387, in <module> main(heartbeat_stop_callback) File "/usr/lib/python2.6/site-packages/ambari_agent/main.py", line 363, in main controller = Controller(config, server_hostname, heartbeat_stop_callback) File "/usr/lib/python2.6/site-packages/ambari_agent/Controller.py", line 67, in __init__ self.version = self.read_agent_version(config) File "/usr/lib/python2.6/site-packages/ambari_agent/Controller.py", line 134, in read_agent_version f = open(ver_file, "r") IOError: [Errno 2] No such file or directory: \'/var/lib/ambari-agent/data/version\' INFO 2017-06-16 17:41:07,060 ExitHelper.py:53 - Performing cleanup before exiting...
