HBASE_CACHE_BLOCKS Query Option
Setting this option is equivalent to calling the setCacheBlocks method of the class org.apache.hadoop.hbase.client.Scan, in an HBase Java application. Helps to control the memory pressure on the HBase region server, in conjunction with the HBASE_CACHING query option.
Type: Boolean; recognized values are 1 and 0, or true and false; any other value interpreted as false
Default: false (shown as 0 in output of SET statement)
