Falcon doesn't start up - HDP 2.3.4 Ambari 2.2

Dear Experts,

I am trying to start Falcon on my cluster (HDP-2.3.4.0-3485, Ambari 2.2), but unfortunately it doesn't start up

I get the following message in the ambari error log:

-----

Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/common-services/FALCON/0.5.0.2.1/package/scripts/falcon_server.py", line 165, in <module>

ImportError: No module named properties_file

Checking the /var/log/falcon directory for logs the directory unfortunately is empty ...

Any hint is appreciated!

Thanks & br,

Rainer

Did it work before? Did service checka pass before? Did you install Oozie? You may need to reinstall it and falcon clients.

@Rainer Geissendoerfer

This is an old thread started by you. https://community.hortonworks.com/questions/14643/spark-thrift-server.html

Are you using the same cluster?

/var/log/falcon - Empty --> Not a good sign

Delete FALCON and try to add again.

It looks like that your cluster is not setup correctly.

curl --user admin:admin -i -H "X-Requested-By: ambari" -X DELETE http://`hostname -f`:8080/api/v1/clusters/CLUSTERNAME/services/FALCON

admin is ambari username and password

No, unfortunately falcon never worked, oozie though is up and running ...

btw I am using a Postgres DB for oozie if that matters by any means ...

I would remove Falcon service and try to add it again

This can be closed ... I had 2 HiveServer2 running on different notes as part of a previously failed hive install ... and this totally confused ranger and falcon ... after removing hive and reinstalling it everything is fine now ... thanks for your support!
