Sanjay Radia commented on HADOOP-4044:
--------------------------------------
Doug says> Sanjay has argued that it is abnormal for a filesystem to link to a
different filesystem. This misses the intended sense of "normal". The value of
a link is normal data, under the control of the filesystem implementation,
regardless of whether it points to a different filesystem.
_Don't want to restart the debate,_ but need to correct something that was
attributed to me:
I never said that symlinks to remote files were not normal. Processing them (ie
following them to a different NN) is not normal for a NN, Some NNs may follow
through and some may not. Indeed DNS does both (follows or redirects the
caller).

> 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.
