             Summary: Coordinator tries to install new view after graceful shutdown
                 Key: ISPN-2186
                 URL: https://issues.jboss.org/browse/ISPN-2186
             Project: Infinispan
          Issue Type: Bug
    Affects Versions: 5.1.6.FINAL (JDG)
            Reporter: Michal Linhard
            Assignee: Manik Surtani
            Priority: Minor


This is not a serious problem, because so far the only thing I discoverd it causes is a superfluous debug level log message.

This happened in elasticity tests with radargun,
In these tests we go from 4 nodes to 8 and back to 4.

See views installed:
http://www.qa.jboss.com/~mlinhard/hyperion2/run218-radargun-08-elasticity-JDG.6.0.1.ER1/report/loganalysis/views.html

In this case, each time the node is shutdown it is the coordinator (I'm not sure whether this is accident or coordinators are picked by their seniority in the cluster)

The shutdown is made gracefully via DefaultCacheManager.stop() and each time this happens I can see an attempt of CacheViewsManagerImpl to install a new view - which doesn't complete because the coordinator shuts down few moments later and the new view is really established by a new coordinator.
