     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.
     1. `fs.seaweed.buffer.size`: Optionally change the default buffer size 4194304 to a larger number. It will be the default chunk size.
     1. `fs.seaweed.volume.server.access`: `[direct|publicUrl|filerProxy]` Optionally access volume servers via their publicUrl settings, or use filer as a proxy. This is useful when volume servers are inside a cluster and not directly accessible.
-    1. `fs.seaweed.filer.cn`: if you have enabled gRPC security on your filer and the certificate doesn't match the hostname of the filer, set this to the CN of your filer's TLS certificate (see [[[[Security-Configuration]], `grpc.filer.cert`). Seaweed doesn't use host name verification anywhere, but Java libraries for gRPC do, so to sidestep this you need to pass them the expected CN instead.
