Re: Mounting a remote Zookeeper

just to clarify the previous proposal. you don't specify which mount
point a file belongs to. you specify which znodes represent a
container entry point (what you are calling a mount point). a znode
will be created in the partition (aka container) that the subtree
belongs to. i believe in this sense the two proposals are both the
same.

Still, I think there are many advantages over the previous namespace partitioning proposal (http://wiki.apache.org/hadoop/ZooKeeper/PartitionedZookeeper) that wasn't implemented AFAIK. The idea here is to make much smaller and more intuitive changes.

Also - in Linux mount you don't need to specify for each new file which mount point the file belongs to - we can exploit the tree structure to infer that instead of creating and maintaining an additional hierarchy like in the previous proposal.
