----------------------------------
Hey Konstantin,
Thanks for posting the overview. Looks good, though it's not just Doug who
would prefer not using exceptions for normal control flow. But aside from the
issue of the use of exceptions is there consensus, eg on the user-visible
behavior of the latest patches? If so, sorry, wasn't clear from the comments.

Apologies for the missing context. Dhruba hasn't had the cycles to close the
jira and I offered to help out. It wasn't clear if people were OK with the
latest patches so I'll work on working on finishing them up so they're
acceptable to people. Yes, I'm committed to supporting the feature.
> My personal preference is approach VI.
Do you mean approach V?
It seems the use of symbolic links will be a common case (eg you can imagine
them being used ala google namespaces) and therefore it would be nice to avoid
multiple round trips to the NN.
Thanks,
Eli

> HDFS should support symbolic links. A symbolic link is a special type of file
> that contains a reference to another file or directory in the form of an
> absolute or relative path and that affects pathname resolution. Programs
> which read or write to files named by a symbolic link will behave as if
> operating directly on the target file. However, archiving utilities can
> handle symbolic links specially and manipulate them directly.
