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

             Summary: RegionCoprocessorHost.execOperation creates too many 
iterator objects
                 Key: HBASE-12748
                 URL: https://issues.apache.org/jira/browse/HBASE-12748
             Project: HBase
          Issue Type: Sub-task
    Affects Versions: 0.98.9, 0.94.25
            Reporter: Vladimir Rodionov
            Assignee: Vladimir Rodionov
             Fix For: 1.0.0, 2.0.0, 0.94.26, 0.98.10


This is typical pattern of enhanced for ... loop usage in a hot code path. For 
every HBase operation it instantiates iterator for coprocessor list twice.
