--------------------------------------
Summary: 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
Reporter: Arun Ravi M V
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.
