      Description

      HBase consistency and availability after replication
      Scene as follows:
      1. There are two HBase clusters are the Master clusters and Slave Clusters. two clusters replication function is open.
      2. if master cluster have problems, so all write and read request switching to the slave cluster.
      3. After a period of time ,we need to switch back to the Master cluster, there will be a part of the data is inconsistent, lead to this part of the data is not available.

      This feature is particularly important for providing online services HBase cluster.
      So, I want through a write-back program to keep the data consistency, then to improve HBase availability.
      we will provide a patch for this function.
