             Summary: Wrapper for leveldb DBIterator to aid in handling 
database exceptions
                 Key: YARN-1987
                 URL: https://issues.apache.org/jira/browse/YARN-1987
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Jason Lowe
            Assignee: Jason Lowe


Per discussions in YARN-1984 and MAPREDUCE-5652, it would be nice to have a 
utility wrapper around leveldb's DBIterator to translate the raw 
RuntimeExceptions it can throw into DBExceptions to make it easier to handle 
database errors while iterating.
