Subject [jira] [Created] (CURATOR-44) LeaderSelector does not assign leader randomly
Date Wed, 26 Jun 2013 23:50:20 GMT
Anders Wallgren created CURATOR-44:

             Summary: LeaderSelector does not assign leader randomly
                 Key: CURATOR-44
             Project: Apache Curator
          Issue Type: Bug
          Components: Recipes
    Affects Versions: 2.0.1-incubating
            Reporter: Anders Wallgren

The javadoc for LeaderSelector says leadership is assigned randomly but this does not appear
to be the case.

A fair mutex is used so it appears that leaders are selected in the order that they attempt
to acquire the mutex.

This probably wouldn't be much more than a documentation issue except that it tends to concentrate
leaders on one node in the cluster when each node participates in more than one election and
tends to start the LeaderSelectors right around the time the node comes up.
