1.安装ceph
2.添加hadoop-ceph.jar
3.hadoop 节点上安装ceph-client

   a)
    ceph osd pool create hadoop1 100
    ceph osd pool set hadoop1 size 1
   b)
     ceph osd dump | grep hadoop1
    $:pool 3 'hadoop1' rep size 1 min_size 1 crush_ruleset 0...
   c)
     ceph mds add_data_pool 3(pool's id)
   d)
    
5.修改hadoop下core-site.xml
  <property>
