Guowei Ma created FLINK-15786: --------------------------------- Summary: Load connector code with separate classloader Key: FLINK-15786 URL: https://issues.apache.org/jira/browse/FLINK-15786 Project: Flink Issue Type: Improvement Components: Runtime / Task Reporter: Guowei Ma
Currently, connector code can be seen as part of user code. Usually, users only need to add the corresponding connector as a dependency and package it in the user jar. This is convenient enough. However, connectors usually need to interact with external systems and often introduce heavy dependencies, there is a high possibility of a class conflict of different connectors or the user code of the same job. For example, every one or two weeks, we will receive issue reports relevant with connector class conflict from our users. The problem can get worse when users want to analyze data from different sources and write output to different sinks. Using separate classloader to load the different connector code could resolve the problem. -- This message was sent by Atlassian Jira (v8.3.4#803005)
