i want to remove all cp of all tables in hbase so i disable tables concurrently, and then modify tables for hundreds of tables, remove all cp costs 30 miniutes, is not so fast
so, i want to speed the whoe process. and will never create/enable tables in the future after examine the code, i want ot increase the pool size for master_table_operation but not sure if there are any problems. thanks..
