Subject hbase0.98.10 online schema modify
Date Thu, 24 Sep 2015 08:27:12 GMT
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?
