-------------------------------------------------------------
Folks, while working to add the "replicas" level to shards (to make room for
other properties), I noticed that the Overseer.updateSlice() method changed the
existing ClusterState (which is advertised as being immutable). I re-wrote the
method to be much shorter, and immutable with respect to the existing
ClusterState, and started getting a test failure.
I eventually tried just adding back the part of the code that erroneously
modified the existing ClusterState, and the test passed again (see the nocommit
block in Overseer).
Any idea what's going on?
edit: the test that failed was LeaderElectionIntegrationTest. Not sure if it
caused other failures.
