> ContainerIds generated by the Local Scheduler on the NM monotonically 
> decrements from 0 to distinguish them from incrementing containerIds 
> generated by the RM.
> Since only the last 40 bits of the ContainerId are actually used, This patch 
> ensures that -1 containerId maps to 2 ^40 -1 and the toString and fromString 
> correctly parses these containerId.
> One implication of this is patch is that the containerId space is divided 
> into 2. The top half will be used by remotely allocated containers and the 
> bottom half by those allocated by the RM
