Till Rohrmann created FLINK-10352: ------------------------------------- Summary: Bind Task's URLClassLoader to TaskExecutor's slot Key: FLINK-10352 URL: https://issues.apache.org/jira/browse/FLINK-10352 Project: Flink Issue Type: Improvement Components: Distributed Coordination Affects Versions: 1.6.0, 1.5.3, 1.7.0 Reporter: Till Rohrmann Fix For: 1.7.0
The {{Task's}} {{URLClassLoader}} is used to dynamically load user code classes. The lifetime of this class loader is bound to the {{Task}} and, thus, it can happen that we generate multiple class loader for the same job if multiple {{Tasks}} are deployed to the same slot successively. We could avoid this situation by binding the lifetime of the {{URLClassLoader}} to the slot instead of the {{Task}}. The slot will only be released if the {{JobMaster}} no longer needs it. That way we won't potentially recreate the {{URLClassLoader}} for every submitted {{Task}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
