Understanding ZooKeeper data file management and LogFormatter

2010-09-08 Thread Vishal K
Hi All, Can you please share your experience regarding ZK snapshot retention and recovery policies? We have an application where we never need to rollback (i.e., revert back to a previous state by using old snapshots). Given this, I am trying to understand under what circumstances would we ever

Yes, Ben, would you give some more details as to why it doesn't work in a cluster? I think I am seeing it work ok in cluster mode as well with some basic tests. There are probably other major problems with this but I would appreciate any direction you could give as to what might go wrong here.

Lock example

2010-09-08 Thread Tim Robertson
Hi all, I am new to ZK and using the queue and lock examples that come with zookeeper but have run into ZOOKEEPER-645 with the lock. I have several JVMs each keeping a long running ZK client and the first JVM (and hence client) does not respect the locks obtained by subsequent clients - e.g. the
