    the naming of these constants is not really in line with their purpose this way. how about
splitting it further and changing the names to ORDER_HOSTS_BY_FREE_CAPACITY_SELECT_CLAUSE
,
    ORDER_HOSTS_BY_FREE_CAPACITY_WHERE_CLAUSE ,
    ...
    ORDER_HOSTS_BY_FREE_CAPACITY_ORDER_BY_CLAUSE ,
    also the conditional part can be defined here
    ORDER_HOSTS_BY_FREE_CAPACITY_CLUSTER_SELECTION = "AND cluster_id = ?";
