>
> When we create local indexes on functions then while joining back missing
> columns from data table is generating wrong data row key.
> When we generated index row key schema we are initializing isNullableToBe to
> true always even if the expression might be not null. Because of this we
> might change the column type to other castable one and may consider actual
> data as separator bytes.
> {noformat}
> ...
> if (indexField == null) {
> Expression e = expressionItr.next();
> isNullableToBe = true;
> dataTypeToBe =
> IndexUtil.getIndexColumnDataType(isNullableToBe, e.getDataType());
> sortOrderToBe = descIndexColumnBitSet.get(i) ? SortOrder.DESC
> : SortOrder.ASC;
> maxLengthToBe = e.getMaxLength();
> scaleToBe = e.getScale();
> ...
> {noformat}
