[infinispan-issues] [JBoss JIRA] (ISPN-4629) Clarify what happens when an available partition and a degraded mode partition merge

[Dan Berindei (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-4629?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dan Berindei resolved ISPN-4629.
--------------------------------
    Fix Version/s: 7.0.0.CR2
                       (was: 7.0.0.Final)
       Resolution: Done


The documentation actually describes how the data on the minority partition will be wiped and it will receive the state from the majority partition. There is also a test for this, ThreeWaySplitAndMergeTest.

> I believe the implementation in https://github.com/infinispan/infinispan/pull/2785 clears the data in the degraded mode partition (since it could be stale) and then rebalances the data from the available partition on all nodes.
> We should add a test to confirm and document it.
