Zookeeper 3.5 stable

Hi,

I've seen that you plan to make 3.5.1 RC soon, but it is not clear for me
when do you plan to publish the 3.5.X stable version. I did not found
usable information in the archived messages, nor on the internet.

I am curious because we shipped a production system with Zookeeper and we
will need the dynamic cluster reconfiguration.

Many thanks,
Joe

Thanks, Vikrant.  We will look into this.

You may try to adjust memory assigned to JVM. I think -Xns is the option 
you may like to use.

Hi Patrick,

Thanks for the link. Based on the archive message the stable 3.5.X version
will not be published within a month, and it is good to know cause we can
design and plan better.
