Zookeeper version and SSL

[Christophe Schmitz]

Hi there,

I would like to use Zookeeper, but I would need SSL support for
client-server encryption.
I found this nice tutorial:
https://cwiki.apache.org/confluence/display/ZOOKEEPER/ZooKeeper+SSL+User+Guide
And it reference JIRA zookeeper-2125
https://issues.apache.org/jira/browse/ZOOKEEPER-2125 which is only fixed
since zookeeper 3.5.1.

Zookeeper main webpage is listing 3.5.0 and 3.5.1 as 'alpha' version. On
the other hand, the github project page has some git tags that seems stable
(release-3.5.1).

So I am wondering if the github tagged version 3.5.1 can be considered
stable at this stage, and if not, if there are some stable way to get ssl
encryption between server and client with a stable version of Zookeeper.

Thanks!

Christophe

Re: Cannot find version in repository

[Rakesh Radhakrishnan]

Hi Sam,

but where can i find log of zookeeper ?

Please refer the "log4j.properties" configuration file. By default its
using CONSOLE appender.
zookeeper.root.logger=INFO, CONSOLE

You can try modifying this to use ROLLINGFILE

Re: Best-practice guides on coordination of operations in distributed systems (and some C client specific questions)

[Alexander Shraer]

for 1, see the chubby paper
,
section 2.4.
for 2, I'm not sure I fully understand the question, but essentially, ZK
guarantees that even during failures
consistency of updates is preserved. The user doesn't need to do anything
in particular to guarantee this, even
during leader failures. In such case, some suffix of operations executed by
the leader may be lost if they weren't
previously acked by a majority.However, none of these operations could have
been visible
to reads.

Re: Cannot find version in repository

[Ted Yu]

>From https://github.com/apache/storm/blob/0.9.x-branch/pom.xml , 3.4.6 is
used.

If you build Storm locally, it would download artifacts for 3.4.6 into
local maven repository.

What I meant in previous email was that 3.4.7 was not stable - see
ZOOKEEPER-2347

Cannot find version in repository

[sam mohel]

I'm new to ubuntu also in zookeeper, I installed storm-0.9.0.1 with
zookeeper-3.4.7

But when i checked this path

.m2/repository/org/apache/zookeeper/

I found zookeeper version 3.3.3 I need to add my version 3.4.7 with all
files it need How can i add it ?

Re: Cannot find version in repository

[Ted Yu]

Was it possible that QuorumPeerMain didn't start ?

Please check the log.

Also use 'ps aux' and search for processes using java.

Cheers

Re: Cannot find version in repository

[Ted Yu]

I assumed you downloaded 3.4.6 from:
https://archive.apache.org/dist/zookeeper/zookeeper-3.4.6/

If you ran zkServer.sh from where 3.4.6 was stored locally, the version
would be 3.4.6

Alternatively, doing 'ps aux | grep 1529' (the pid for QuorumPeerMain)
would show you the path.

Cheers
