Thanks
Enrico Olivelli
Hi,
is there any way to see in JMX which is the leader of a ZooKeeper cluster?
My problem is: given access to any of the nodes of the cluster I want to
know from JMX which is the current leader.
It seems to me that this information is not available, you can know only if
the local node is Leader
which is the leader from its point of view.
>From your answer I guess that the final answer is no.
I did not check the code, if the change is minimal (I guess the follower
knows which is the current leadger) I can work on a patch

problem is mostly about configuring HDFS?
Kerberos/SASL config is only a matter of setting jaas.conf and the keytabs,
I don't know how to give good referenced for HDFS

If a node has children it cannot be deleted, so maybe the solution for you
is to create a special "root" node, like
/myapp and set ACLs on it and on every children.
This is actually what I am doing.

It depends on your use case.
Auth is required mostly in conjunction with ACLs, so you can have client
which perform auth and clients without auth.
This is useful during the transition from no-ACL to an ACL based database.
Hope that helps

Can you describe better your problem ?
Usually you are activating auth on clients and then you apply the ACLs this
way all clients will be able to access data.
Try our procedure in a staging environment before doing in in production

Hello,

If you have 3 servers you can nuke the broken one and make it start from

servers

We must ensure that that change does not break 100% compatibility with 3.4

The best way to prove it is to setup some integration test that tests a

As Jorn said you should introduce some kind of scalable middleware.
Zookeeper shouldn't be used in the hotpath.
If you want something simple and based on components from Zookeeper
ecosystem maybe you can give a look to this simple task broker service,

Zili,
Sessions expire in the server. If you are not connected to the cluster you
cannot assume that the session is expired.
There is another weird edge case: if the server/cluster is down the session
cannot expire.

IIRC in my company we set up some ZK with TLS and SASL, using TLS for
encryption and SASL for auth.
We were using early 3.5.3 or something like that.
Do you have a specific error?
I can also add that in 3.6.0 we will have port-unification, this way you
can configure only one client port

If you only want to run the server you just need the binary package.
A common practice is to rename the zoo_sample.cfg file to zoo.cfg and the
run the server
Running zkServer.sh from the sources requires to build the sources with
mvn clean install -DskipTests

This 'null' looks like a NullPointerException (this kind f exceptions

Can you find some full stacktrace of the error?
Are you able to enable more detailed logging?
Do you see errors on the client (kafka broker?) ? Maybe on
Matthew,
can you share some logs ?
That issue is quite generic, and it describes a case that usually works as
expected (= system works fine)
It is very common to bounce a server in a cluster of three, so there must
be a cause for your problem.
In a 3 nodes clusters usually you can continue

The release branch 3.4 is frozen and we should cut new releases only for
important security reasons or other important issues for users that cannot
upgrade to 3.5.
Given that 3.5 is now the suggested version and the upgrade path is simple
I think there is no need to put effort into this activity.
I think it is possible to perform a rolling upgrade from 3.4, all of my
customers migrated one year ago and without any issue (reported to my team).
Norbert, where did you find that information?
btw I would like to setup tests about backward compatibility,

The Apache ZooKeeper team is proud to announce Apache ZooKeeper version 3.6.0.
ZooKeeper is a high-performance coordination service for distributed
applications. It exposes common services - such as naming,
configuration management, synchronization, and group services - in a
simple interface so
No, sorry.
But CVE-2019-17571 does not affect neither Zookeeper client nor Zookeeper
server.
We have an open ticket about this problem.
Probably we will move to slf4j on 3.7.
In case any help or contribution in this direction will be very appreciated

If you are upgrading a very short lived cluster (no snapshot on server data
directory) you should upgrade to 3.5.7 (not 3.5.6 or less).
There was an important issue in the upgrade procedure that has been fixed
in 3.5.7

ACLs are your way to go

Hi,
Which version of ZK are you using?

There is a method to force JAAS to reload the system property.
Something like Configuration.getConfiguration().refresh()
You have to call that method after changing the system property
Hope that helps

If you try it and report that it is working for you, this will be a good
contribution to the community

Arpit,
Up to 3.5.x you can only leverage auth only in conjunction with ACLs.
I hope we are able to release 3.6.0 within a couple of weeks.
If you have time you can build from branch-3.6 and run the server enabling
that feature tha you are pointing to.
It is a server side change only so you can
