Ankit Singhal created HIVE-18873:
------------------------------------

             Summary: Skipping predicate pushdown silently at HiveInputFormat 
can cause storage handlers to produce erroneous result
                 Key: HIVE-18873
                 URL: https://issues.apache.org/jira/browse/HIVE-18873
             Project: Hive
          Issue Type: Bug
    Affects Versions: 3.0.0
            Reporter: Ankit Singhal
            Assignee: Ankit Singhal
             Fix For: 3.0.0


{code:java}
// disable filter pushdown for mapreduce when there are more than one table 
aliases,

    // since we don't clone jobConf per alias

    if (mrwork != null && mrwork.getAliases() != null && 
mrwork.getAliases().size() > 1 &&

      jobConf.get(ConfVars.HIVE_EXECUTION_ENGINE.varname).equals("mr")) {

      return;

    }
{code}
I believe this needs to be handled at OpProcFactory so that hive doesn't 
believe that predicate is handled by storage handler.
