We are trying to ... 1. Use the G1 garbage collector for smaller stop-the-world GC pauses. 2. Obtain verbose logs from Ignite for troubleshooting purposes
We have tried setting IGNITE_JVM_OPTS="-DIGNITE_QUIET=false -XX:+UseG1GC", but the JVM options are not taking effect on the Server nodes. Please help.

We are using Ignite as a Distributed In-Memory cache, deployed using YARN on a Hadoop Cluster. We have configured Zookeeper Discovery, and this is working fine. Given this is a small 20 node Ignite cluster, Zookeeper Discovery seems overkill. Would it be possible to switch to TCP Discovery? Multicast Finding is not an option, as that is disabled. Static IP Finding would also not work, as the Ignite Containers are dynamically allocated by YARN to arbitrary nodes of the Hadoop Cluster.
