Hoss Man updated SOLR-5823:
---------------------------
Attachment: SOLR-5823.patch
I tried testing this in conjunction with SOLR-5795 and ran into all sorts of
problems, which lead me to discover SOLR-5919: when using
AbstractFullDistribZkTestBase, the controlClient acts as the overseer, and none
of the regular nodes in the (test) cluster do (evne though neither the control
server nor the cluster nodes seem to think the control server is part of the
cluster ... i don't understand it)
here's an updated patch that includes an "IsOverseerTest" subclassing
AbstractFullDistribZkTestBase and demonstrating the problem with the test
framework in SOLR-5919 ... this depends on a change to SystemInfoHandler to
surface the "isOverseer()" info so lcinets can ask about it -- something i'm
not sure if we really want, but it was the only way i could figure out to write
a test that demonstrated this aspect of the problem.
> Add utility function for internal code to know if it is currently the overseer

> It would be useful if there was some Overseer equivalent to
> CloudDescriptor.isLeader() that plugins running in solr could use to know "At
> this moment, am i the leader?"
