Sumit Kumar commented on HADOOP-10643:
--------------------------------------
[~ste...@apache.org] I'm assuming your concern is on this portion of the patch
(as part of AbstractFileSystem.java):
{noformat}
- // A file system implementation that requires authority must always
- // specify default port
- if (defaultPort < 0 && authorityNeeded) {
- throw new HadoopIllegalArgumentException(
- "FileSystem implementation error - default port " + defaultPort
- + " is not valid");
- }
{noformat}
If so, s3's urls have a specific requirement that they don't contain any port
(so defaultPort becomes -1 in this case) and they don't have any authority in
the url as well. Does this work?
> Add NativeS3Fs that delgates calls from FileContext apis to native s3 fs
> implementation

>
> 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.
