Hi,   In the demo here: http://gethue.com/hadoop-tutorial-monitor-and-get-alerts-for-your-workflows-with-the-oozie-slas, there is a comment in the text: “We do not cover setup of JMS notifications here. JMS enables clients to be alerted in real time of the notifications (instead of pooling like in this tutorial). With Hue, you can visualize the success of your job in a timelime and setup email-notification in case of alerts.”   Could someone clarify this for me? What I need to know is: do I need to setup JMS notifications in order for the email-notification to work? Or is it just sufficient to enter the email adress in Hue? Is there any other configuration needed for emails, e.g. set up of SMPT server details in cloudera manager etc?   Thanks in advance to anyone who can help! ... View more

When I submit the workflow, I can see the SLA settings in the definition and the SLA tab appears but the tab is empty except for a back button.   Here is my SLA: <sla:info> <sla:nominal-time>${nominal_time}</sla:nominal-time> <sla:should-start>${10 * MINUTES}</sla:should-start> <sla:should-end>${30 * MINUTES}</sla:should-end> <sla:max-duration>${30 * MINUTES}</sla:max-duration> <sla:alert-events>start_miss,end_miss,duration_miss</sla:alert-events> <sla:alert-contact>myname@mycompany.com</sla:alert-contact> <sla:notification-msg>[Hadoop] Error while calculating reference measurements</sla:notification-msg> </sla:info>   As well as the page being blank, I receive no email (have previously verified that emails can be sent via oozie actions, so the configuration should be ok) and no SLA appears under the SLA tab in the Dashboard ...
