Collecting performance metrics for impala

Hi,

 

I'm wondering if there is any impala jmx that can shows the memory /cpu use per query, so i can collect metrics per user or pool,

Input tables are coerced into the OS buffer cache. Output tables are on disk (Impala has no notion of a cached table).
