Description

NameNode HA cluster was created via blueprint with specifying 'dfs_ha_initial_namenode_active' and 'dfs_ha_initial_namenode_standby' properties for hadoop-env with invalid values 'None'.
Afterwards ambari upgrade from 2.6.* to 2.7.5 was failed with following stacktrace:

ERROR [main] SchemaUpgradeHelper:240 - Upgrade failed. 
java.lang.IllegalArgumentException: NAMENODE HA hosts mapped incorrectly for properties 'dfs_ha_initial_namenode_active' and 'dfs_ha_initial_namenode_standby'. Expected hosts are: [<nnHAHost1>, <nnHAHost2>]
