Subject [jira] [Commented] (AMBARI-2451) Enhance host checks in the api for more checks on the host - users/ntp/others.
Date Mon, 24 Jun 2013 18:47:22 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-2451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13692242#comment-13692242
] 

Siddharth Wagle commented on AMBARI-2451:
-----------------------------------------

+  TIMEOUT_SECONDS = 60
Is this something we can read from config? 

+        osStat = subprocess.Popen(["service", service, "status"], stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
"service" command assumes a script to be present under /etc/init.d/"service", Does this cover
all scenarios that you are looking for?

+        if not 'AmbariServer' in cmd:
Can this be a configurable expression? Increases extensibility for future use.

+  RESULT_UNAVAILABLE = "unable_to_determine"
Should this be "skipping determination"? Sounds like error message.
