回复: Can hierarchyDims contain jointDims
So what's the second code segment mean in AggregationGroup build step?
is it means replace the hierarchy dim with the joint dims witch contain it?

Joint could not be used in the hierarchy.
Joint means treating multiple dimensions as one: they either all appeared, either all not; It is a conflict with hierarchy.

HI ALL:
I read the src code of kylin 2.2, and find:
In class CubeDes, if hierarchyDims contain jointDims will throw exception.
public void validateAggregationGroups() {
...
if (CollectionUtils.containsAny(hierarchyDims, jointDims)) {
logger.error("Aggregation group " + index + " hierarchy dimensions overlap with joint dimensions");
throw new IllegalStateException(
"Aggregation group " + index + " hierarchy dimensions overlap with joint dimensions: "
+ ensureOrder(CollectionUtils.intersection(hierarchyDims, jointDims)));
}
But in class AggregationGroup will replace the hierarchy dim with the joint dims witch contain it.
private void buildHierarchyMasks(RowKeyDesc rowKeyDesc) {
.....
for (int i = 0; i < hierarchy_dims.length; i++) {
TblColRef hColumn = cubeDesc.getModel().findColumn(hierarchy_dims[i]);
Integer index = rowKeyDesc.getColumnBitIndex(hColumn);
long bit = 1L << index;
// combine joint as logic dim
if (dim2JointMap.get(bit) != null) {
bit = dim2JointMap.get(bit);
}
mask.fullMask |= bit;
allMaskList.add(mask.fullMask);
dimList.add(bit);
}
}
do i understand in a wrong way?

So this issues is work in progress, and result in the two piece contradict code. thank you for make me clear.
