------------------------------------------

             Summary: Possible tx desync during recovery on near node left.
                 Key: IGNITE-12548
                 URL: https://issues.apache.org/jira/browse/IGNITE-12548
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.7.6
            Reporter: Alexey Scherbakov
            Assignee: Alexey Scherbakov
             Fix For: 2.9


The problem appears if a transaction is starting to rollback in PREPARED state for some reason and concurrently near node is left triggering tx recovery protocol.

Consider having two enlisted keys from different partitions mapped to different nodes N1 and N2.

Due to race N1 local tx can be rolled back while N2 local tx is committed breaking tx atomicity guarantee.
