Hi,
Could you please help me with a basic query regarding 'zkServer.sh status' ?

local node and get info.
If the local server is down, does it connect to next available server (as
specified in config file ) and returns
Hi Ram,
ZooKeeper Quorum authentication support two schemes, Kerberos or
DIGEST-MD5. User has to configure either Kerb or digest configuration
values. Both together not required.
I'd recommend you to go through Kerberos, digest simulation unit test cases

3.5.6 will automatically create a clean snapshot as part of server start up
process. So a snapshot should be available after initial upgrade and there
is no need to force a snapshot creation.

based on the logs, it seems working. It is great to see that you will use
it :) Let us know if you would see any issue with it.
FYI, we already have a few improvements under review around these areas:

Hi,
we're working on securing our clusters. For quorum, once we set
sslQuorum=true, there is no more unsecured quorum port.
Is such an option available or in the works for the client port as well ?
Or is ssl client port always in addition to unsecured client port ?

Flavio,
Thanks for clarification, I have a cluster with sasl disabled but in start
up log I still see number of threads set to default 20.
Thanks,

If it is just logging the value of the property, then it is fine because the
property is set, but it is not used if SASL is disabled.

Hi Ram,
Yes, this parameter is only applicable when SASL is enabled, see in
QuorumCnxManager#initializeAuth how it doesn't have a chance to use the
parameter when SASL is disabled.
Your assessment is correct about it being based on the number of participants,
excluding observers. This
Hi Chris,
The short answer is yes, all you need to do is don't specify the clientPort
in the zoo.cfg.
An example for the zoo.cfg in this case:
tickTime=3000
initLimit=10
syncLimit=5
dataDir=/data/zkdata
secureClientPort=2191
serverCnxnFactory=org.apache.zookeeper.server.NettyServerCnxnFactory
Kudos to everyone!
Also, nice to see so many contributions. And not just veterans, but plenty
of new community members! Thank you all!

If you set up logging at DEBUG level and you see this message:
"Not initializing connection executor as quorum sasl auth is disabled"
then you are good.
