    Some of the concourse feature tests failed with this commit. There are some other place use these guc name with the prefix 'hawq_'. So what about keep the prefix in the hawq-site.xml and add the prefix to the guc in guc.c ? This can reduce the work to find all the places use the several guc you changed and keep the name consistently with other gucs name.

    @radarwave  In my investigate, I found that hawq read these GUCs from a config file which set these values when init, since there is no database to store them before init.  Maybe no one config / show them using hawq config or they use option "--skipValidation". No one change and no one hit this problem, only some warnings exist in logs.  No function read "dfs_url" "master_directory" "seg_directory". 
    But RM function sendIMAlive() will use "standby_addr_host" and I haven't found the reason. Maybe @jiny2 knows why.

    I find there is some python script logic using the hawq_* guc names, I will keep those hawq_* guc names to avoid changing python scripts.

    LGTM.
    
    Just wondering how hawq read these mis-match GUCs before you change them? Seems they still can get the right values.

    In fact some gucs are not used by reading from hawq-site.xml, for example, hawq_master_directory. But for standby_addr_host, it is useful for RM as RM switches its heart-beat to standby server when master server is not achievable.

    @huor @stanlyxiang @paul-guo- 
    
    @stanlyxiang  is right, the correct approach is to fix guc.c as all external scripts and documentation are using hawq_* names.

    1) Please make sure the doc has corresponding change if needed (notify them if needed). If I remember correctly, dfs_url is still in that doc.
    2) Please make the commit message begin with HAWQ-1242 since we have a script, which needs this pattern, to detect the Apache JIRA status.
