Steve Loughran commented on HADOOP-10643:
-----------------------------------------
Sumit -why did you cut a check from {{AbstractFileSystem}}? That could have
implications elsewhere.
This should be retained, otherwise we've added a new way for things to fail,
different error messages, etc.
Can you add a new protected method to validate the URI; something which does
the check —and which your code overrides if it really, really doesn't want a
port to be specified. That won't impact anything else.
> Add NativeS3Fs that delgates calls from FileContext apis to native s3 fs

> The new set of file system related apis (FileContext/AbstractFileSystem)
> already support local filesytem, hdfs, viewfs) however they don't support
> s3n. This patch is to add that support using configurations like
> fs.AbstractFileSystem.s3n.impl = org.apache.hadoop.fs.s3native.NativeS3Fs
> This patch however doesn't provide a new implementation, instead relies on
> DelegateToFileSystem abstract class to delegate all calls from FileContext
> apis for s3n to the NativeS3FileSystem implementation.
