--------------------------------------
Thanks Ted,
Yep, will add the license header. This was just to get a general feeling for
whether the logic is even correct... Dealing with ZK correctly is tricky.
bq. Should shared data provide putIfAbsent() functionality ?
Not sure what you mean. It does (the interface it exposes is a ConcurrentMap as
per HBASE-6505). Do you think it should not?
Will add Thread.interrupt (I keep forgetting about that :( ).
