>          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.
