Enable symlinks 

hi,

anyone know how to enable symlinks in HDFS?

I call it FileSystem.enableSymlinks() in client side,and try to create a symlink, it throw following exceptions:

org.apache.hadoop.ipc.RemoteException: Symlinks not supported
        at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.createSymlink(FSNamesystem.java:2009)
        at org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.createSymlink(NameNodeRpcServer.java:963)

        at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1556)
        at org.apache.hadoop.ipc.Server$Handler.run(Server.java:2007)

I go through all source code, don't find how to enable it.

Anyone knows?

Thanks in advance.

Tang.

Hadoop does not currently support symlinks.  Hence the "Symlinks not
