> For now, hdfs cacheadmin can not set a default replication num for cached
> directive in the same cachepool. Each cache directive added in the same cache
> pool should set their own replication num individually.
> Consider this situation, we add daily hive table into cache pool "hive" .Each
> time i should set the same replication num for every table directive in the
> same cache pool.
> I think we should enable setting a default replication num for a cachepool
> that every cache directive in the pool can inherit replication configuration
> from the pool. Also cache directive can override replication configuration
> explicitly by calling "add & modify directive -replication" command from
> cli.
