> The exception can be reproduced using following code in HiveDialectITCase
> {code:java}
>  HiveModule hiveModule = new HiveModule(hiveCatalog.getHiveVersion());
>  CoreModule coreModule = CoreModule.INSTANCE;
>  for (String loaded : tableEnv.listModules()) {
>    tableEnv.unloadModule(loaded);
> }
> tableEnv.loadModule("hive", hiveModule);
> tableEnv.loadModule("core", coreModule);
> List<Row> results = CollectionUtil.iteratorToList(tableEnv.executeSql("select bround(55.0, -1)").collect());
> {code}
> It will case such exception "BROUND second argument only takes constant", the reson is the parameter "-1" will be considered as function call instead of contant, we should fold it in HiveParserTypeCheckProcFactory#getXpathOrFuncExprNodeDesc.
