 * Configure Hadoop to use SeaweedFS in `etc/hadoop/conf/core-site.xml`. `core-site.xml` resides on each node in the Hadoop cluster. You must add the same properties to each instance of `core-site.xml`. There are several properties to modify:
     1. `fs.seaweedfs.impl`: This property defines the Seaweed HCFS implementation classes that are contained in the SeaweedFS HDFS client JAR. It is required.
     1. `fs.defaultFS`: This property defines the default file system URI to use. It is optional if a path always has prefix `seaweedfs://localhost:8888`.
+    1. `fs.AbstractFileSystem.seaweedfs.impl`: Add the SeaweedFS implementation of Hadoop AbstractFileSystem to delegates to the existing SeaweedFS FileSystem and is only necessary for use with Hadoop 3.x.
