Apache Mesos Framework support scheduling and running Apache Ignite nodes in a Mesos cluster. This develop a Mesos Scheduler, a Mesos Task.
User starts Ignite Mesos Framework, framework scheduler is started and registers in the Mesos Cluster. Once registration is successful the framework will start to launch tasks on nodes. The framework will begin expanding the cluster to the desired total number of nodes. If a node were to be lost, the framework would first attempt to restart the node and the framework will remove the lost node from the cluster.
Multiple instances of the framework can be run for multiple topology Frameworks will re-register with Mesos. Fault Tolerant, to restart failed Apache Ignite node tasks.
The Mesos scheduler is the component with the most high-level intelligence in the framework. It will need to possess the ability to start Apache Ignite cluster and distribute the correct configuration and packages to all started nodes.
The Mesos Task will be responsible for running container with required configuration.
1. Build ignite-mesos module.
2. Run IgniteFramework use the followin command.
java -jar ignite-mesos-1.0.0-snapshot-jar-with-dependencies.jar
3. To make sure that Framework running. Open Mesos console at http://<master-ip>:5050
4. Go to sandbox
5. Look at stdout
and stderr
logs.
The following properties can be used to configure the framework. The properties can be passed to how property of file or environment variables.
