Robert Kanter commented on OOZIE-1616:
--------------------------------------
Ok, then I'll wait on updating this patch until after OOZIE-1519 is in. I
thought that the Instrumentation stuff repopulated all of its values every
minute, but it looks like it doesn't for "variables". I can add an
{{updateVariable(...)}} method to do that.

Another general question - how does the instrumentation show up in HA mode for
different oozie servers?
{quote}
Each server has its own Instrumentation, which makes sense because they may not
be homogeneous (e.g. different amounts of Memory). If the user is accessing
Oozie through a load balancer, or some other round-robin thing, then every time
they refresh the page, they will possibly hit a different Oozie server and see
differences in the instrumentation info in the UI. I think that's fine because
its really more of an admin thing and if someone is really interested in these
values they would be interested in a specific Oozie server and can just go to
that server directly instead of through the load balancer. Alternatively, we
could try to have a way of displaying subtabs (one for each server) on the UI
and have the REST command return an array of servers and their instrumentation
info.

> It would be convenient to add the sharelib and launcher lib locations to the
