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 have set up Tomcat cluster, behiind Apache Httpd server, with 2 nodes. I read the Tomcat documentation at Tomcat cluster how to and the first requirement is:"All your session attributes must implement java.io.Serializable". I've done and session replication, failover mechanism seems to work. Now I'm using a framework for Web app develop and it seems that the object classes that are stored in the session don't implement Serializable. I'm looking for a workaround to solve this problem in the simplier manner. I've read a lot of questions/answer but not solution so far. Any idea? Tomcat version 7.0.76. Thank you.
I tried setting up an Apache Storm Cluster, using Apache Storm 1.0.2 and Zookeeper 3.4.9. Everything worked fine, but I realized that Apache Samoa - What I'm going to use the Cluster for - is only compatible with versions of Apache Storm <1.0.0.
Thus, I downgraded all of the Apache Storm nodes to Apache Storm 0.9.4, but none of the nodes could connect to the Zookeeper. Is Apache Storm 0.9.4 only compatible with older versions of Zookeeper? If so, does anybody know what version of Zookeeper I should use?
I'm extremely new to this so forgive me for any incorrect terminology, etc, I use.
Thanks for all your help!
I figured out the issue regarding my connection issues (It's unrelated to the main question). But, I can confirm that Apache Storm 0.9.4 is compatible with Zookeeper 3.4.9.
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 .
Currently i am searching for possible Clustering technologies usable by Apache Axis2 servers. I know that WSO2 Platform uses Apache Tribes for their Servers which are based on Axis2? I want to know if there is an alternative to Apache Tribes for Clustering?
We actually also tried JGroups .. but AFAIK, it did not workout very well.
Are you guys are hitting a problem with Tribes based implementation? Within WSO2 platform, tribes has worked out very well.
We are also looking into the possibility of writing a ZooKeeper based clustering implementation.
i want to know how to configure haproxy and rabbitmq.i want to make my rabbitmq more scalable and available....
any link any idea anyone have
There is a tutorial provided by the RabbitMQ folks to do HA/Failover.
They use DRBD and Pacemaker, you can have a look at the link provided.
