[jira] [Created] (HIVE-17916) remove ConfVars.HIVE_VECTORIZATION_ROW_IDENTIFIER_ENABLED

Eugene Koifman created HIVE-17916:
-------------------------------------

             Summary: remove ConfVars.HIVE_VECTORIZATION_ROW_IDENTIFIER_ENABLED
                 Key: HIVE-17916
                 URL: https://issues.apache.org/jira/browse/HIVE-17916
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 3.0.0
            Reporter: Eugene Koifman
            Assignee: Teddy Choi


follow up from HIVE-12631.  Filing so it doesn't get lost.

There is this code in UpdateDeleteSemanticAnalyzer
{noformat}
      // TODO: remove when this is enabled everywhere
	      HiveConf.setBoolVar(conf, ConfVars.HIVE_VECTORIZATION_ROW_IDENTIFIER_ENABLED, true);
{noformat}
The 1st update/delete statement on a session will enable this and it will be enabled for all future queries which makes this flag useless/misleading.
