Bikramjeet Vig 1c94450ca9 IMPALA-7353: Improve memory estimates for Hbase Scan Nodes

Currently for hbase scan nodes we use a constant estimate of 1GB which
is generally a gross over-estimation. This patch improves upon those
estimates by using huerestics based on how hbase rows are stored and
fetched and how the scanners interact with the internal memory pool.

Testing:
Added/Modified resource requirements planner test.
Added a junit test for the estimation logic.

README

This directory contains Impala test workloads. The directory layout for the workloads should follow:

workloads/
   <data set name>/<data set name>_dimensions.csv  <- The test dimension file
   <data set name>/<data set name>_core.csv  <- A test vector file
   <data set name>/<data set name>_pairwise.csv
   <data set name>/<data set name>_exhaustive.csv
   <data set name>/queries/<query test>.test <- The queries for this workload
