You overflowed integer type positive numbers range. You have to convert it to
long value explicitly:
<property name="maxSize" value="#{2L * 1024 * 1024 * 1024}"/>

As the ‘maxSize' javadoc and the documentation I shared before say:
If the overall memory usage goes beyond the maximum size parameter then an out
of memory exception will be thrown. To avoid this use an eviction algorithm or
set the size to a bigger value.

You need to set MemoryPolicyConfiguration.setMetricsEnabled to true. Read more
here:
https://apacheignite.readme.io/v2.0/docs/memory-and-cache-metrics#section-memory-metrics
<https://apacheignite.readme.io/v2.0/docs/memory-and-cache-metrics#section-memory-metrics>
If this helps then let me know. I think we need to set this parameter to true
automatically if cache metrics are enabled.
