Subject [jira] [Created] (IGNITE-4632) AffinityFunction unchecked exception handling (unassigned backup)
Date Wed, 01 Feb 2017 05:01:51 GMT
Alexandr Kuramshin created IGNITE-4632:
------------------------------------------

             Summary: AffinityFunction unchecked exception handling (unassigned backup)
                 Key: IGNITE-4632
                 URL: https://issues.apache.org/jira/browse/IGNITE-4632
             Project: Ignite
          Issue Type: Bug
          Components: general
    Affects Versions: 1.8
            Reporter: Alexandr Kuramshin
            Priority: Minor


{{AffinityFunction}} implementation may throw unchecked exception upon assignment. In some
cases additional processing should be performed when affinity function method invocation throws
an exception.

Special case when the cache with backups is running, and a node with a primary partition will
left. Then we get the primary partition unassigned if {{AffinityFunction.partition(Object)}}
throws an exception. My suggestion is to shutdown the node in such the case (like SEGMENTED),
because the cluster could not work normally without the primary partition assigned.
