Subject [jira] [Created] (DRILL-1567) Pushdown fails with WHERE clause with more than one AND or OR operator of same type
Date Wed, 22 Oct 2014 07:01:33 GMT
Aditya Kishore created DRILL-1567:
-------------------------------------

             Summary: Pushdown fails with WHERE clause with more than one AND or OR operator
of same type
                 Key: DRILL-1567
                 URL: https://issues.apache.org/jira/browse/DRILL-1567
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - HBase
    Affects Versions: 0.6.0
            Reporter: Aditya Kishore
            Assignee: Aditya Kishore
             Fix For: 0.7.0


The HBase filter push-down code assumes that there could be only 2 operands for an AND or
OR operator and in care of multiple AND/OR conditions, it will be presented as operator tree
with two operands at each level.

However, if there are two or more AND/OR operator of the same kind (either all AND or all
OR), Optiq combines them as a single Boolean operator.
