    #### will be created. The number of locations in the list dictate
    #### the number of primary segments that will get created per
    #### physical host (if multiple addresses for a host are listed in 
    #### the hostfile, the number of segments will be spread evenly across
    #### the specified interface addresses).
    declare -a DATA_DIRECTORY=(/data/gpdb/gpdata2/gpdatap1 /data/gpdb/gpdata2/gpdatap2 /data/gpdb/gpdata2/gpdatap3 /data/gpdb/gpdata2/gpdatap4)


    #### OS-configured hostname or IP address of the master host.
    MASTER_HOSTNAME=mdw


    #### File system location where the master data directory 
    #### will be created.
    MASTER_DIRECTORY=/data/gpdb/gpdata2/gpmaster


    #### Port number for the master instance.

    #### numbers are calculated. 
    MIRROR_REPLICATION_PORT_BASE=51000


    #### File system location(s) where mirror segment data directories 
    #### will be created. The number of mirror locations must equal the
    #### number of primary locations as specified in the 
    #### DATA_DIRECTORY parameter.
    declare -a MIRROR_DATA_DIRECTORY=(/data/gpdb/gpdata2/gpdatam1 /data/gpdb/gpdata2/gpdatam2 /data/gpdb/gpdata2/gpdatam3 /data/gpdb/gpdata2/gpdatam4)


    ################################################
    #### OTHER OPTIONAL PARAMETERS
    ################################################


    #### Create a database of this name after initialization.
