> Error output from schema upgrade command:

> Error occurs in UpgradeCatalog240.upgradeCapSchedulerView(), here :
> {code}
> clusterEntity.setPassword(new
> DefaultMasker().unmask(propertyMap.get("ambari.server.password")));
> {code}
> because all properties in {{propertyMap}} has null value.
> In general this method "upgradeCapSchedulerView" was added to upgrade CUSTOM
> capacity scheduler view to Remote but "if" construction is not complete.
> Because when we are doing cluster name update, {{cluster_handle}} column will
> not be updated correctly(for ambari 2.2.2). So later during upgrade when you
> changing {{cluster_name}} from string to int(cluster id) nothing will be set
> in this column.
