[jira] [Created] (HDFS-7988) Replace usage of ExactSizeInputStream with LimitInputStream.

Chris Nauroth created HDFS-7988:
-----------------------------------

             Summary: Replace usage of ExactSizeInputStream with LimitInputStream.
                 Key: HDFS-7988
                 URL: https://issues.apache.org/jira/browse/HDFS-7988
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Chris Nauroth
            Priority: Minor


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.
