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.
