in hbase0.98.10, we can modify table-descriptor without disable table. in the past, if we want to add cp to a table, we can do like this: 1. disable table 2. add cp 3. enable table
now, we can add cp directly without disable table, but, when master modify table, it will re-open all regions of this table finally regions will be close and open. so, what beneift can we get if we use online schema? wangyongqiang0...@163.com
