Hi, would work nicely. Who would own the parent node after the session that created the initial pair exits (assume additional children exist)? On 23 March 2010 02:42, Benjamin Reed br...@yahoo-inc.com wrote: let me put out an idea that we have kicked around for a while: ephemeral containers.

Excellent idea Jeff. Dominic feel free to open 2 JIRAs, one for ephem in ephem and a second for the weak watchers. Summarize your goals and the discussion so far as appropriate. BTW, either of these JIRAs would be good for a new contributor interested in gaining experience with ZooKeeper.

It is difficult for me to make up my mind as I feel I don't have enough information to decide. Right now it feels that there is no concrete major benefit to move to TLP status. My impression is that the Hadoop PMC has represented us well and helped us all along, so I believe our position

I agree with Ben here. I think we do need sometime to get more bodies contributing to the ZooKeeper codebase. Being a subproject of Hadoop gives us quite a few benefits like branding/discoverability (as Pat mentioned). These benefits are important to us given our small developer base and the
