主要是会影响到Context的划分，Kap IT下面的这些Query会出现问题：

org.apache.kylin.query.ITKylinQueryTest#testGroupingQuery
io.kyligence.kap.ITKapKylinQueryTest#testMagine（sql-04）
io.kyligence.kap.ITKapKylinQueryTest#testMultiModelQuery（sql-01）
org.apache.kylin.query.ITKylinQueryTest#testSubQuery（query03）
org.apache.kylin.query.ITKylinQueryTest#testValues（query01）

解决办法：
将这个树生成DAG的commit revert掉，c0f912d

[CALCITE-2116] In HepPlanner, ensure that common sub-expressions have the same digest (LeoWangLZ)"
This reverts commit c0f912d.
