> In Hadoop a lot of optimization has been done in namenode data structures to be memory
efficient. Similar optimizations are necessary for Datanode process. With the growth in storage
per datanode and number of blocks hosted on datanode, this jira intends to optimize long lived
ReplicasMap and ReplicaInfo objects.
