      Description

      Allow bucketcache use more than just one backing file: e.g. chassis has more than one SSD in it.

      Usage (Setting the following configurations in hbase-site.xml):

      <property>
      <name>hbase.bucketcache.ioengine</name>
      <value>files:/mnt/disk1/bucketcache,/mnt/disk2/bucketcache,/mnt/disk3/bucketcache,/mnt/disk4/bucketcache</value>
      </property>
      <property>
      <name>hbase.bucketcache.size</name>
      <value>1048576</value>
      </property>

      The above setting means the total capacity of cache is 1048576MB(1TB), each file length will be set to 0.25TB.
