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

             Summary: too many locks acquired?
                 Key: HIVE-14770
                 URL: https://issues.apache.org/jira/browse/HIVE-14770
             Project: Hive
          Issue Type: Bug
          Components: Transactions
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


need to verify

UpdateDeleteSemanticAnalyzer.reparseAndSuperAnalyze() has
{noformat}
    if (inputIsPartitioned(inputs)) {
      // In order to avoid locking the entire write table we need to replace 
the single WriteEntity
      // with a WriteEntity for each partition
      outputs.clear();
      for (ReadEntity input : inputs) {
        if (input.getTyp() == Entity.Type.PARTITION) {
          WriteEntity.WriteType writeType = deleting() ? 
WriteEntity.WriteType.DELETE :
              WriteEntity.WriteType.UPDATE;
          outputs.add(new WriteEntity(input.getPartition(), writeType));
        }
      }
    } else {
{noformat}

but this seems to assume that each partition read is also written

shouldn't this check isWritten()?  see HIVE-11848
