With the uploaded v4 patch,  we could config the single file or multi-files as the following
{quote}
 <name>hbase.bucketcache.ioengine</name> 
 <value>file:/mnt/disk1/bucketcache</value>

 <name>hbase.bucketcache.ioengine</name> 
 <value>file:/mnt/disk1/bucketcache,/mnt/disk2/bucketcache,/mnt/disk3/bucketcache</value>
{quote}

Could you take a look?  Thanks.
