LevelDB setup
I'm trying to setup a leveldb cluster on Redhat 3 node cluster.
I have ActiveMQ 5.12.1 zookeeper 3.4.6 installed but I keep getting this
error.
INFO | Initiating client connection,
connectString=appdev041.corp.local:2181,appdev042.corp.local:2181,appdev043.corp.local:2181
sessionTimeout=2000
watcher=org.apache.activemq.leveldb.replicated.groups.ZKClient@745e3cad
WARN | Could not login: the client is being asked for a password, but the
Zookeeper client code does not currently support obtaining a password from
the user. Make sure that the client is configured to use a ticket cache
(using the JAAS configuration setting 'useTicketCache=true)' and restart the
client. If you still get this message after that, the TGT in the ticket
cache has expired and must be manually refreshed. To do so, first determine
if you are using a password or a keytab. If the former, run kinit in a Unix
shell in the environment of the user who is running this Zookeeper client
using the command 'kinit <princ>' (where <princ> is the name of the client's
Kerberos principal). If the latter, do 'kinit -k -t <keytab> <princ>' (where
<princ> is the name of the Kerberos principal, and <keytab> is the location
of the keytab file). After manually refreshing your cache, restart this
client. If you continue to see this message after manually refreshing your
cache, ensure that your KDC host's clock is in sync with this host's clock.
WARN | SASL configuration failed: javax.security.auth.login.LoginException:
No password provided Will continue connection to Zookeeper server without
SASL authentication, if Zookeeper server allows it.
My loging.config is configured :
activemq-domain {
org.apache.activemq.jaas.PropertiesLoginModule required
org.apache.activemq.jaas.properties.user="users.properties"
org.apache.activemq.jaas.properties.group="groups.properties";
};
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=false
useTicketCache=true;
};
My activemq.xml is set to:
<jaasAuthenticationPlugin configuration="activemq-domain" />
and
<persistenceAdapter>
<replicatedLevelDB directory="activemq-data" replicas="3"
bind="tcp://0.0.0.0:0"
zkAddress="appdev041.corp.local:2181,appdev042.corp.local:2181,appdev043.corp.local:2181"
zkPassword="password" zkPath="/activemq/leveldb-stores"
hostname="appdev041.corp.local"/>
</persistenceAdapter>
I'm not sure what's going on thanks for the help.
Thanks
Mike

Have you seen
http://www.elasticcloudapps.com/page0/files/c1f6bea32e025aa68542a95f9d664ea9-12.html?
I only skimmed it, but it looks detailed enough to be promising.

Could you share your zookeeper conf please.
Is password authentication of zookeeper configured?

BTW, did you see this in the error message? "If you continue to see this
message after manually refreshing your
cache, ensure that your KDC host's clock is in sync with this host's
clock." Is there a time difference between your clocks?

Thanks for reaching out Tim.
I would prefer not to use Kerberos right now but I have no examples to
follow.
I'm just want to get something running so I can run some fail-over tests.
I tried the link but looks like I would have to install Kerberos Servers
etc.
I'll reach out to the zookeeper mailing list thanks again.
Mike

Unfortunately the mailing list doesn't have an active LevelDB expert; when
people ask LevelDB questions, they generally go unanswered.
In this case, it's possible I might be able to help. Looking at your first
error message, it appears to be a Kerberos error, and I see what looks like
a Kerberos configuration block, but let's make sure: are you in fact trying
to use Kerberos authentication?
Assuming you are, have you followed the instructions in the error message?
Also, when I Googled for that error message and the word Kerberos, this was
in the first page of search results and provided both a useful debug flag
and a potential solution:
http://efod.se/blog/archive/2015/04/30/zookeeper-kerberos
If that problem turns out not to be resolved by either of the things I
listed above, you should post your question to the Zookeeper mailing list
(I'm assuming there is one), since the problem you're hitting appears to be
purely a Zookeeper problem rather than a LevelDB problem.

Does anyone have an example of setting up LevelDB other then the ActiveMQ web
site?
I followed them and can't get this to work.
Thanks
