-# Set in_memory=true and blockcache=true on catalog tables.
-# The .META. and -ROOT- tables can be created with caching and
-# in_memory set to false.  You want them set to true so that
-# these hot tables make it into cache.  To see if the
-# .META. table has BLOCKCACHE set, in the shell do the following:
-#
-#   hbase> scan '-ROOT-'
-#
-# Look for the 'info' column family.  See if BLOCKCACHE => 'true'? 
-# If not, run this script and it will set the value to true.
-# Setting cache to 'true' will only take effect on region restart
-# of if you close the .META. region -- *disruptive* -- and have
-# it deploy elsewhere.  This script runs against an up and running
-# hbase instance.
-# 
-# To see usage for this script, run: 
-#
-#  ${HBASE_HOME}/bin/hbase org.jruby.Main set_meta_block_caching.rb
