             Summary: [table] Using Table API to perform aggregation on another 
Table API / SQL result table causes runVolcanoPlanner failed on physicalPlan 
generation
                 Key: FLINK-7177
                 URL: https://issues.apache.org/jira/browse/FLINK-7177

          Issue Type: Bug
            Reporter: Rong Rong


For example:
```
val env = ExecutionEnvironment.getExecutionEnvironment
val tEnv = TableEnvironment.getTableEnvironment(env, config)
val inputTable = 
CollectionDataSets.getSmallNestedTupleDataSet(env).toTable(tEnv, 'a, 'b)
val resultTable = inputTable.select('a, 'b).where('a.get("_1") > 0)
val failingTable = resultTable.select('a.get("_1").avg, 'a.get("_2").sum, 
'b.count)
```
