Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-18631
https://issues.apache.org/jira/browse/AMBARI-18631
Repository: ambari
Description
-------
Currently the database consistency check runs as a separate process prior
Ambari process. The database consistency checker load various modules needed
for performing the validations. (e.g. load stack definitions to be able to
compare service configs from stack with configs from db).
Once database consistency checker completed Ambari server is started. Ambari
server beside others loads the same modules as database consistency checker.
This double initialisation adds time to the ambari server startup time which
could be reduced if the database consistency check is moved into the ambari
server process.
Moreover the database consistency check may check at the beginning if the
database is empty and perform the checks only if there is data in the database.
