Konstantin Shvachko commented on HDFS-4559:
-------------------------------------------
Suresh, it was true that symLinks were exposed only through FileContext, but
not any more. Once creating a symLink is exposed through WebHdfs it should also
support resolving symLinks and reading data through them.
This could be either done solely for WebHdfs or universally exposed through
FileSystem. So we can close one of the two jiras, but need to fix the other
one. I would rather add support for symLinks through FileSystem, otherwise the
feature is rotting and not widely used.
Plamen, "Fix Version/s:" field should be only filled when the jira is resolved.
Use "Target Version/s:" to indicate versions you want it to be fixed in.

> WebHDFS allows you to create symlinks via the CREATESYMLINK operation, but
> the GETFILEINFO operation specifically calls the getFileInfo() method of the
> NameNodeRpcServer which does not resolve symlinks.
> I propose adding a parameter to GETFILEINFO such that if true will call
> getFileLinkInfo() rather than getFileInfo() which will resolve any symlinks.
