Andrew Wang updated HADOOP-8040:
--------------------------------
Attachment: hadoop-8040-2.patch
New consolidated patch, hopefully hit all the test-patch errors. Revved the
patches on the sub-JIRAs as well.
One further caveat I wanted to ask about: {{FileSystem#create}} always creates
parents, and we instead have a separate, deprecated {{createNonRecursive}}
method. {{FileSystemTestWrapper}} currently calls plain {{#create}} and I
forcibly ignore symlink tests that check the non-recursive behavior. If it's
okay to use the deprecated function, I can switch it to use
{{createNonRecursive}} and re-enable the ignored test.
> Add symlink support to FileSystem

> HADOOP-6421 added symbolic links to FileContext. Resolving symlinks is done
> on the client-side, and therefore requires client support. An HDFS symlink
> (created by FileContext) when accessed by FileSystem will result in an
> unhandled UnresolvedLinkException. Because not all users will migrate from
> FileSystem to FileContext in lock step, and we want users of FileSystem to be
> able to access all paths created by FileContext, we need to support symlink
> resolution in FileSystem as well, to facilitate migration to FileContext.
