I am trying to install HDP in a single node for development (Ambari agent and host on the same node, also all the components). I am using the default guides and documentation from Hortonworks but I am stuck after installing the components. After installation of Apache Ambari (2.7.1.0) and HDP stack (HDP-3.0.1.0 [3.0.1.0-187]), services can't start. even after installation or after a reboot and manual request. Ranger fails to start, then the next procedures stop due to a timeout in the Ambari operation. I suppose the same situation will apply for the other services (except for those already running) Where I can diagnose the applications or the OS to unlock this issue? I am sure it is not an Ambari bug but it must be something from my OS. I have tried other suggestions from similar issues but with success. Firewall is disabled by default. Also, I am using PostgreSQL as DB support. Here are the command outputs: Step 9 of Cluster wizard: stderr: Traceback (most recent call last): File "/var/lib/ambari-agent/cache/stacks/HDP/3.0/services/RANGER/package/scripts/ranger_tagsync.py", line 133, in RangerTagsync().execute() File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 354, in execute self.execute_prefix_function(self.command_name, 'post', env) File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 378, in execute_prefix_function method(env) File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 420, in post_start raise Fail("Pid file {0} doesn't exist after starting of the component.".format(pid_file)) resource_management.core.exceptions.Fail: Pid file /var/run/ranger/tagsync.pid doesn't exist after starting of the component.
