--------------------------------
Summary: LogicalNode misses some fields when it converts to json
Key: TAJO-92
URL: https://issues.apache.org/jira/browse/TAJO-92
Project: Tajo
Issue Type: Bug
Components: optimizer
Reporter: hyoungjunkim
See title. The below code reproduces the error
{code}
PlanningContext context = analyzer.parse(
"select table0.age, count(*) as count_age from table0 group by
table0.age");
LogicalNode plan = logicalPlanner.createPlan(context);
plan = LogicalOptimizer.optimize(context, plan);
String planJSON = plan.toJSON();
LogicalNode planFromJSON = GsonCreator.getInstance().fromJson(planJSON,
LogicalNode.class);
MasterPlan globalPlan = planner.build(queryId, (LogicalRootNode)
planFromJSON);
