Subject [jira] [Commented] (AIRAVATA-1615) Please have clear notification on PGA when compute resources are under maintenance
Date Fri, 01 Apr 2016 14:40:25 GMT

    [ https://issues.apache.org/jira/browse/AIRAVATA-1615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15221776#comment-15221776
] 

Eroma commented on AIRAVATA-1615:
---------------------------------

In current AIravata 0.16 we print job submission response and in this scenario user will receive
information on response message as well as in the error from Airavata server.
Till further improvement this is  sufficient.

Also Super admins can disable unavailable compute resources across gateways.

these types of notifications should be displayed in the PGA home page or can even be alerted
users via email.
