I am wondering if it's possible to start an Apache Ignite client Node by passing configuration parameters to the JVM. For instance, we may start a server Node by running "org.apache.ignite.startup.cmdline.CommandLineStartup" and passing config parameters to it.

I know it's possible to start a Node from inside a class implementation by initializing Ignite interface and explicitly joining a Cluster.

The easiest way to start a client node is invoke the Ignition.start(..) method. For more details you can refer to any example shipped with Ignite and to this documentation page: https://apacheignite.readme.io/docs/clients-vs-servers

I am aware of this option, but that's not what I wanted. For instance Oracle Coherence allows to start Node by passing Cluster and Cache configuration parameters to the JVM. Is there such an option in Ignite?
What exactly do you mean by "passing Cluster and Cache configuration parameters to the JVM"? Can you give an example?
Sure. In Coherence I can pass "-Dtangosol.coherence.override" property to the JVM which essentially tells my particular JVM to join a Cluster and become either a client or server node. I don't need to code anything at this time. I am wondering if Ignite provides something similar to that.
What is the purpose of a client node that is not running within an application? I'm not sure about Coherence, but I doubt that it makes any sense in context of Ignite. To start a standalone server node you can use ignite.sh|bat script providing an XML configuration file as a parameter.
I can think of at least one situation where I would prefer to start a client node in advance. I would rather know in advance that my client was not able to join a Cluster than at runtime. Of course, ignite.sh works perfectly fine. Thank you.

You can write a wrapper java class of your own which will take JVM params and then call org.apache.ignite.startup.cmdline.CommandLineStartup or any client api required to start the ignite client.

`public void main(String[] args) {

String property = System.getProperty("property");

}` pass the xml file or properties received to System.getProperty("name") using org.apache.ignite.startup.cmdline.CommandLineStartup
