[jira] [Created] (HADOOP-18476) Abfs and S3A FileContext bindings to close wrapped filesystems in finalizer

Steve Loughran created HADOOP-18476:
---------------------------------------

             Summary: Abfs and S3A FileContext bindings to close wrapped filesystems in finalizer
                 Key: HADOOP-18476
                 URL: https://issues.apache.org/jira/browse/HADOOP-18476
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/azure, fs/s3
    Affects Versions: 3.3.4
            Reporter: Steve Loughran
            Assignee: Steve Loughran


if you use the FileContext APIs to talk to abfs or s3a, it creates a new wrapped FileSystem implementation, and, because there is no close() call, never cleans up.

proposed: add finalizers for these two classes, which we know create helper threads, especially if plugins are added
