> We can rely on
> https://github.com/apache/hive/blob/master/llap-server/src/java/org/apache/hadoop/hive/llap/IncrementalObjectSizeEstimator.java
> to estimate memory of SharedCache. This jira addresses the size estimation
> during prewarm, so that we can stop when we hit the memory limit. In a
> follow-up jira, we will work on estimation/eviction after prewarm is
> complete, so that we can keep the frequently used tables and their partitions
> in cache.
