> After investigation, I figured out, that in our tests when we trying to setup config on Oozie tab application replaces the correct Oozie DB URL with the wrong one.
> You can see this on video 1:07-1:11. 
> Looks like StackAdvisor response received twice.
> When we choose "Existing MySQL/MaridDB Database" Database URL property changed according the value with "Oozie Server host", test changed it as needed (according to pattern)
> OOZIE_DB_URL = "jdbc:mysql://" + AmbariProperties.INSTALL_EXTERNAL_DB_HOST_NAME + "/" + "ooziedb";
> and immediately this property was changed to the old one
> go to HDFS configs
> in chrome dev console select Network, set throttling -> GPRS
> change "NameNode Java heap size"
> go to Advanced (config tab) and change "NameNode new generation size"
> once you will get response for recommendations, value of "NameNode new generation size" will be changed to recommended one
> If you have bad internet connection you can make a stack of recommendation requests, that will hang in pending state, and once resolved will apply recommended values
