> HDFS has a class named {{ExactSizeInputStream}} used in the protobuf translation layer.  This class wraps another {{InputStream}}, but constraints the readable bytes to a specified length.  The functionality is nearly identical to {{LimitInputStream}} in Hadoop Common, with some differences in semantics regarding premature EOF.  This issue proposes to eliminate {{ExactSizeInputStream}} in favor of {{LimitInputStream}} to reduce the size of the codebase.
