zhijiang created FLINK-12735: -------------------------------- Summary: Make shuffle environment implementation independent with IOManager Key: FLINK-12735 URL: https://issues.apache.org/jira/browse/FLINK-12735 Project: Flink Issue Type: Sub-task Components: Runtime / Network Reporter: zhijiang Assignee: zhijiang
The current creation of {{NetworkEnvironment}} is relying on {{IOManager}} from {{TaskManagerServices}}. In order not to rely on external specific components for implementing shuffle environment, and let the specific implementation creates internal components if required. The current abstract {{IOManager}} has two roles, one is for file channel management based on temp directories configuration, and the other is providing abstract methods for reading/writing files. We could further extract the file channel management as a separate internal class which could be reused for all the required components, like current {{BoundedBlockingSubpartition}}. To do so, the shuffle environment should also creates its internal channel manager to break dependency with {{IOManager}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
