Since there is error during > planning, we want to see the sets in the exception message, but when dumping > Graphviz, it might encounter another exception (we can't guarantee all the > sets and subsets are correctly generated for Graphviz), causing failure to > dump Sets info, which is rather helpful in production system. > {code:java} > Caused by: java.lang.AssertionError > at > org.apache.calcite.util.PartiallyOrderedSet.findParentsChildren(PartiallyOrderedSet.java:318) > at > org.apache.calcite.util.PartiallyOrderedSet.findParents(PartiallyOrderedSet.java:308) > at > org.apache.calcite.util.PartiallyOrderedSet.add(PartiallyOrderedSet.java:226) > at > org.apache.calcite.plan.volcano.VolcanoPlanner.dumpGraphviz(VolcanoPlanner.java:1320) > at > org.apache.calcite.plan.volcano.VolcanoPlanner.dump(VolcanoPlanner.java:1194) > at > org.apache.calcite.plan.volcano.RelSubset$CheapestPlanReplacer.visit(RelSubset.java:606) > at > org.apache.calcite.plan.volcano.RelSubset.buildCheapestPlan(RelSubset.java:307) > at > org.apache.calcite.plan.volcano.VolcanoPlanner.findBestExp(VolcanoPlanner.java:649) > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
