> The LRFU cache policy for the LLAP data cache doesn't provide enough insight
> to figure out, what is cached and why something might get evicted. This
> ticket is used to add Hadoop metrics 2 information (accessible via JMX) to
> the LRFU policy, providing following information:
> * How much memory is cached for data buffers
> * How much memory is cached for meta data buffers
> * How large is the min-heap of the cache policy
> * How long is the eviction short list (linked list)
> * How much memory is currently "locked" (buffers with positive reference
> count) and therefore in use by a query
> These new counters are found in the MX bean, following this path:
> Hadoop/LlapDaemon/LowLevelLrfuCachePolicy-<hostname>
