Description

I have attempted to install Oozie with Postgres db backend via HDP 2.4. I was able to test DB connection via Ambari, everything was correct. However, the server failed to start with this error:

Schema verification at startup worked fine and I could not find any bugs related to it. So, I started getting suspicious about my password value, which was like "pO,e43DpjK" (not exactly but it was a bunch of letters, number and one comma). I suspected that the comma was probably interpreted as a value list separator so I have changed the password removing the comma. Server started flawlessly.

I am not 100% sure if it is Ambari that should be escaping (or validating?) the value or Oozie that fails to read the value as single string.
