yangzhg opened a new issue #3195: CrossJoinNode not implement computeStats
URL: https://github.com/apache/incubator-doris/issues/3195
`computeStats` in CrossJoinNode is overrided by empty node .This will cause numberNodes and cardinality is always 0.
Especially when corss join node is a child of a hashjoin node, the roadcastCost is `broadcastCost = rhsDataSize * leftChildFragment.getNumNodes();` so roadcastCost will always 0 too
