功能说明
确保所有数据rebalance 完成后，可以将旧的distribution 删掉，将被替换节点从虚
拟集群中移除。
操作步骤
步骤1：将旧的distribution（Distribution ID 3）删掉，将被替换节点从虚拟集群中
移除。
$ gcadmin rmdistribution 3 vc vc1
cluster distribution ID [3]
it will be removed now
please ensure this is ok, input [Y,y] or [N,n]: y
select count(*) from gbase.nodedatamap where data_distribution_id=3 result is
not 0
refreshnodedatamap drop 3 success
gcadmin remove distribution [3] success
完成后的集群信息如下：
$ gcadmin
