-------------------------------

             Summary: [UDF]the same qualified class name is in different jar, 
create function should return error
                 Key: IOTDB-4949
                 URL: https://issues.apache.org/jira/browse/IOTDB-4949
             Project: Apache IoTDB
          Issue Type: Bug
    Affects Versions: 0.14.0-SNAPSHOT
            Reporter: changxue
            Assignee: Yuan Tian
         Attachments: SameNameTest.java, normla-udf-0.14-SNAPSHOT.jar, 
same-name-test-0.14-SNAPSHOT.jar

[UDF]the same qualified class name is in different jar, create function should 
return error

There is a class name "SameNameTest", it both in normla-udf-0.14-SNAPSHOT.jar 
and 

same-name-test-0.14-SNAPSHOT.jar. But they are not the same, the first one is 
for boolean value and later one is for int32.

I create my UDF with "SameNameTest" class successfully and it uses the one in 
normla-udf-0.14-SNAPSHOT.jar.

 

reproduction:
 # put the attachment jars in $IOTDB_HOME/ext/udf
 # execute sql command below:
{code:sql}
drop function my_test;
create function my_test as "SamNameTest";

create database root.same;
create timeseries root.same.test.s1 with datatype=boolean;
create timeseries root.same.test.s2 with datatype=int32;
insert into root.same.test(time, s1, s2) values (1,true,32),(2,false,12);

-- 使用的是normal-udf内的而不是 same-name-test内的
select my_test(s1) from root.same.test;
select my_test(s2) from root.same.test;

drop function my_test;
drop database root.**;{code}

 

message in command window:
{code:sql}
select my_test(s1) from root.same.test
Time(TIME)      |my_test(root.same.test.s1)(INT32)      |
总数目：0

select my_test(s2) from root.same.test
SQLSTATE : 416: Error occurred during inferring UDF data type:
org.apache.iotdb.udf.api.exception.UDFInputSeriesDataTypeNotValidException: the 
data type of the input series (index: 0) is not valid. expected: BOOLEAN. 
actual: INT32.
