Leo Zhang created FLINK-14319:
---------------------------------
Summary: Register user jar files in {Stream}ExecutionEnvironment
Key: FLINK-14319
URL: https://issues.apache.org/jira/browse/FLINK-14319
Project: Flink
Issue Type: New Feature
Components: API / DataSet, API / DataStream
Reporter: Leo Zhang
Fix For: 1.10.0
I see that there are some use cases in which people want to implement their
own SQL application based on loading external jars for now. And the related API
proposals have been issued in the task FLINK-10232 Add a SQL DDL .
And the related sub-task FLINK-14055 is unresolved and its status is still
open. I feel that it's better to split this task FLINK-14055 into two goals,
one for DDL and the other new task for
\_{Stream\}ExecutionEnvironment::registerUserJarFile()_ interface.
I have implemented the interfaces both for java and scala API, and they are
tested well. And my implementation exactly obeys to the design doc of the
FLINK-10232 and chooses the first option from design alternatives. So I wanna
share my codes if it's ok.
