---------------------------------------
Summary: CPP: Do not start JVM if it is already started
Key: IGNITE-4618
URL: https://issues.apache.org/jira/browse/IGNITE-4618
Project: Ignite
Issue Type: Task
Components: platforms
Affects Versions: 1.8
Reporter: Vladimir Ozerov
Assignee: Igor Sapego
Fix For: 1.9
*Problem*
Consider the following scenario:
1) User's app started JVM in the process somehow.
2) User tries to start the node.
3) Result: exception.
*Solution*
We need to check if JVM is already started. If yes - then try re-using. Note
that we are likely to fail at this point because user might forgot to pass
proper Ignite classpath. In this case we must throw extremely sensible
exception, so that user understand how to fix the problem right away.
E.g.: "Failed to start Ignite node with already started JVM due to invalid
classpath; please add the following JARs to the classpath: [PATH TO IGNITE_HOME
JARS]".
