Subject [GitHub] accumulo issue #242: ACCUMULO-2181/3005 REST API and new Monitor UI
Date Wed, 24 May 2017 17:42:48 GMT
Github user joshelser commented on the issue:

    https://github.com/apache/accumulo/pull/242
  
    > What has changed is that the standby serves the REST API and views instead of displaying
a message that it does not have the lock, while it is waiting for the lock.
    
    An old, standby monitor would return HTTP/503 (unavailable) to signify that it isn't polling
data from the master and (thus) is useless to observe. Does the new REST API still do this?
    
    I am thinking that the test could hit the REST API (instead of a view) to get the same
HTTP/503, and the view could display its message about "i am the standby-monitor, blah blah"
in response to the 503?
    
    Aside: I'm finding the use of 503 to denote "expected unavailability" to be odd (i'm used
to 5xx series being unexpected server-side errors) despite using that code when writing this
:). I wonder if there is a 4xx response code which would be more appropriate.
