Description

The FSNamesystem.processReport() method converts the blocklist for a datanode into an array by calling node.getBlocks(). Although this memory allocation is transient, it could possibly require the garbage-collector to work that much harder.

The method Block.getBlocks() should be deprecated. Code that currently uses this method should instead iterate over the Collection.
