Date Fri, 17 Mar 2017 01:46:41 GMT

]

chunhui shen updated HBASE-15314:
---------------------------------
    Description: 
Allow bucketcache use more than just one backing file: e.g. chassis has more than one SSD
in it.

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


  was:Allow bucketcache use more than just one backing file: e.g. chassis has more than one
