Subject Re: Ignite 2.7.0 YARN deployment - IGNITE_JVM_OPTS doesn't seem to work
Date Wed, 06 Nov 2019 12:12:09 GMT
Hello!

You should use Static IP Finder without specifying any hosts, Yarn launcher
will pass the list of hosts to discover via environment variable.

IGNITE_JVM_OPTS should work. Please try to debug this issue, file a ticket
against IGNITE JIRA if you have any specifics.

Regards,
