Re: Question about Barrier tutorial

[Flavio Junqueira]

The one in the tutorial is not optimized, so the way to differentiate the nodes is by appending the node name, and not sequential identifiers. -Flavio On Feb 22, 2011, at 10:07 AM, ChingShen wrote: Hi Flavio,   I think I got it, I get the Barrier code from (http://zookeeper.apache.org/doc/r3.3.1/zookeeperTutorial.html#sc_barriers) that create a EPHEMERAL_SEQUENTIAL znode rather than EPHEMERAL znode, it's maybe a documentation bug.

The leave() method serves that purpose.
