Harvey Yue commented on KYLIN-4455:
-----------------------------------

In OLAPProjectRel, we added kylin mesure columns to AbstractRelNode#rowType and 
the RexNodes to OLAPProjectRel#rewriteProjects instead of Project#exps, but the 
Project#exps is final property, we couldn't to reassign the new RexNode to 
exps, so when printing plan occur the 

exception: Caused by: java.lang.IndexOutOfBoundsException: index (3) must be 
less than size (3)

> Query will fail when set calcite.debug=true
