> 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.
