      Description

      To enable hot standby namenode, the standby node must have current information for - namenode state (image + edits) and block location information. This jira addresses keeping the namenode state current in the standby node. To do this, the proposed solution in this jira is to use a shared storage to store the namenode state.

      Note one could also build an alternative solution by augmenting the backup node. A seperate jira could explore this.
