大数据 灾备
The basis of this solution is to have one or more mirror Hadoop clusters which will be continuously
updated with the data from the primary cluster in either a synchronous method or an asynchronous
method by utilizing and improving the existing HA feature, data block replication and data block
pipelining. In this solution, we support both synchronously writing and asynchronously replication
across datacenters for both namespace and data block.
