             Summary: [UDF]Using UDF on a non-existent timeseries, should return error
                 Key: IOTDB-4932
                 URL: https://issues.apache.org/jira/browse/IOTDB-4932
             Project: Apache IoTDB
          Issue Type: Bug
    Affects Versions: 0.14.0-SNAPSHOT
            Reporter: changxue
            Assignee: Yuan Tian


[UDF]Using UDF on a non-existent timeseries, should return error

reproduction:
{code:java}
create function my_sum as "com.timecho.udf.normal.MySum";

-- root.abcdefg does not exist.
select my_sum(s1) from root.abcdefg.dddd; {code}

It should return an error, because the database ,the device and the timeseries are not existed. 
We are trying getting data from a non-existent database, the database system should tell us it's not correct to do this.
