             Summary: Race condition of deletingTxIDs between readOnlyIterator 
and onFlush
                 Key: HDDS-15665
                 URL: https://issues.apache.org/jira/browse/HDDS-15665
             Project: Apache Ozone
          Issue Type: Improvement
            Reporter: Sammi Chen
            Assignee: Sammi Chen


While readOnlyIterator returns an iterator for getTransactions to use, 
readOnlyIterator skips elements which are already in deletingTxIDs, while 
before readOnlyIterator is closed, another thread can call onFlush to cleanup 
the deletingTxIDs, causing finished transactions be loaded again for delete.
