> 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
> Priority: Minor
> 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.
> {code}
