Example 6 with ColumnAccessInfo

use of org.apache.hadoop.hive.ql.parse.ColumnAccessInfo in project flink by apache.

the class HiveParserCalcitePlanner method logicalPlan.

        semanticAnalyzer.columnAccessInfo = new ColumnAccessInfo();
    }

        } else if (ctasCols != null) {
            // CTAS doesn't allow specifying col list, so we set it according to result schema
