> *Steps*
> # Deploy HDP- cluster with Ambari 2.2.2
> # Upgrade Ambari to
> # Register HDP- version and install the bits
> # Modify configs for some of the service like HDFS, ZK, YARN
> # Start EU
> *Result*:
> EU pre-check does *not* report below error for the three services whose config was modified
in step 4
> "The following service configurations have been updated and their Service Checks should
be run again:"
> Upon further investigation found that the pre-check does not work if a service check
has never been run for a service at all AND reports success in such cases
> In other words, the comparison between last config modification time and last service
check time succeeds if service check never ran at all and the output of below query returns
> {code}
> SELECT start_time FROM host_role_command where role = 'HDFS_SERVICE_CHECK' AND status
> {code}
> In this case when I manually ran a service check for HDFS and retried EU, the pre-check
caught the mismatch and reported error
> *Note*: I believe we do run service check as part of cluster install, but looks like
it does not get updated in the DB tables for all services.
