I am new to zookeeper and after weeks of reading documentations and I got confused with its concepts.
Acoording to me,
Zookeper provides set of apis so that we can make use of it to
co-ordinate the distributed application.
Anyone correct me if I am wrong.
Zookeeper is about distributed computing
Good tutorials
1)https://www.youtube.com/watch?v=2RfBHqDWa60
2)Why do we need ZooKeeper in the Hadoop stack?
3)https://www.igvita.com/2010/04/30/distributed-coordination-with-zookeeper/
4)http://zookeeper.apache.org/doc/r3.4.2/index.html
Hope that helps
You are absolutely right ..
Zookeeper is also used for configuration management in distributed applications .
Go through hadoop book (2009-Book-Hadoop the Definitive Guide )to know more about zookeeper .

I'm setting up the infrastructure for a Ray project and would like to use an external redis (i.e one not started by ray --head. However that currently does not seem possible, giving me:
If --head is passed in, a Redis server will be started, so a Redis address should not be provided.
Has anyone managed to use an external Redis not managed by Ray?
Regards,
Niklas
There's an ongoing project to improve this limitation. https://github.com/ray-project/ray/pull/6763
The idea is to make GCS as a service that you can use various external backends.
Does any one have any good tutorials of Apache Ignite.There seems to be very few practical tutorials or articles of Apache Ignite.
Have you seen Getting Started on readme.io?
Please indicate what you are missing from there.
I am using Ehcache in my application. I need to monitor cache statistics using JMX. Ehcache provides an api net.sf.ehcache.management for the same.
Please let me know, how to proceed further?
Documentation on this topic can be found here, it should give you insights on what you need to do.
I have been tasked with integrating ActiveMQ with Weblogic (v 10.3.6.0).
I have downloaded ActiveMQ v 5.10.0, installed it upon the server and browsed to localhost:8161/admin in order to confirm that ActiveMQ is running.
I'm not sure how to progress from here in order to complete my goal. This link:
http://activemq.apache.org/weblogic-integration.html
.. suggests that there are two approaches to deploying ActiveMQ on Weblogic: either deploying a broker as an application or using a J2EE Connector. I'm investigating the latter approach as I have now installed ActiveMQ on the server (which means that I already have a running broker, I assume) but can't find much useful information on the Net about how to do this.
This page:
http://activemq.apache.org/resource-adapter.html
... suggests that it can be done via a JCA Resource Adapter but again does not give any details on how to do it.
If anyone has any advice or guidance, I'd appreciate it.
Thanks in advance.
Did you try this: http://activemq.apache.org/how-to-deploy-activemq-ra-versionrar-to-weblogic.html?
You will have to grab the resource adapter from maven.
Not that your local installation will help you much expect for testing etc. You should deploy AMQ inside WebLogic if you want it to serve as the JMS layer of WebLogic - otherwise a totally standalone installation is fine. But then you're done, and I suspect you want the deployed version non the less.
I want to implement High availability for Rabbitmq server.i have read the Rabbitmq provide document,on document is use DRBD,i don't wants to use DRBD for share storage,from my side i have did clustering with two node and prepare mirror queue.
rest needs to be implemented high availability help me.
Thanks
The HA documentation can be found on the RabbitMQ site at
http://www.rabbitmq.com/ha.html
with the main set up being described in
http://www.rabbitmq.com/clustering.html
This doesn't involve DRBD and is simply a guide on how to mirror queues across multiple servers.
I have implemented a HA rabbit cluster based on the instructions in the above so I can attest to their clarity.
If you have any specific questions regarding HA setup that isn't clear from the above then I'm happy to answer them.
