Arun Ravi M V resolved HADOOP-16540.
    Resolution: Won't Fix

> Pluggable Filesystem Caching Support in FileSystem Class
> --------------------------------------------------------
>                 Key: HADOOP-16540
>                 URL: https://issues.apache.org/jira/browse/HADOOP-16540
>             Project: Hadoop Common
>          Issue Type: New Feature
>          Components: fs
>    Affects Versions: 3.3.0
>            Reporter: Arun Ravi M V
>            Priority: Major
> Provide an option to use Custom Cache Class in FileSystem Class. Currently, the caching
is enabled by default and uses the URI schema and authority value to determine whether to
create a new FS instance for the given URI or to fetch an already existing one from the cache.
> In case of AWS S3 FS Impl, for an S3 path, the authority name will be bucket name, ie
Filesystem object will be cached at the bucket level, but providing a custom caching logic
can empower the user to cache it at some prefix level and provide more flexibility.
