patches that aren't in ZK core. So I was maintaining an internal fork at work. Also, my duties at work changed last winter and I'm no longer working on .Net things so I've had limited time to do a ZK 3.5.x upgrade myself or work on my Curator port to .Net. -- Kathryn Hogg Senior Technology

Thanks! That buys me some time from having to fork ZookeeperNetEx and do a 3.5.x port myself. Additionally, it should allow me to use Kafka with a 3.5.x zookeeper. -- Kathryn Hogg Senior Technology Architect -Original Message- From: Andor Molnar [mailto:an...@apache.org] Sent

RE: About ZooKeeper Dynamic Reconfiguration

2019-08-21 Thread Kathryn Hogg
At my organization we solve that by running a 3rd site as mentioned in another email. We run a 5 node ensemble with 2 nodes in each primary data center and 1 node in the co-location facility. We try to minimize usage of the 5th node so we explicitly exclude it from our clients' connection

If we are running zookeeper on virtual machines, what is the recommended best practice in regards to the transaction log directory? We can create a dedicated virtual disk for the transaction logs but what if that vdi/vmdk file is sitting on the same drive on the host OS? -- Kathryn Hogg Open
