> The heap size can be configured via JAVA_TOOL_OPTIONS. Configuring the JVM heap size is likely a common task when deploying Impala containers to production because the catalogd and coordinators need to be sized to fit the working set of metadata - it would be worthwhile to have a more explicit and clearly-documented way to set the heap size.
> We could also try to be fancy and choose a heap size based on the container memory limit and the role of the container.
