CDAP master is not able to come up with "explore.service" is disabled.
In environments where hive is disabled, we can not enable explore service. Because we cannot enable explore service, its value is set to false. As a result, CDAP master service does not come up.
It gives the error:
Runnable explore.service is not defined in the application
Attached the screenshot of error message.
In YarnTwillPreparer.java confirmRunnableName(String runnableName), throws this error.
