Description

It seems, due to latest changes HBase predicate pushdown is not getting applied.

In below snippet, "le.accept(this, null)" returning null.

  public HBaseScanSpec parseTree() {
    HBaseScanSpec parsedSpec = le.accept(this, null);
    if (parsedSpec != null) {
      parsedSpec = mergeScanSpecs("booleanAnd", this.groupScan.getHBaseScanSpec(), parsedSpec);
      /*
       * If RowFilter is THE filter attached to the scan specification,
       * remove it since its effect is also achieved through startRow and stopRow.
       */
      if (parsedSpec.filter instanceof RowFilter) {
        parsedSpec.filter = null;
      }
    }
    return parsedSpec;
  }
