>
> This feature introduces physical memory monitoring in SamzaContainer.
> Context:
> Often memory used by the SamzaContainer process includes
> A. JVM Heap memory: This is where all JVM variables live.
> B. Native memory: This memory lives out of the JVM heap and is not visible to
> the JVM. Examples include used by RocksDb, native libraries that user code
> depends on etc.
> User jobs could be killed by Yarn if their total memory (A+B) exceeds the
> configured maximum of yarn.container.memory.mb.
> Currently, while our existing metrics provide visibility into [A] via JMX, we
> don't have visibility into [B]. (as it's totally external to the JVM).
