[jira] [Created] (HADOOP-11674) data corruption for parallel CryptoInputStream and CryptoOutputStream

Sean Busbey created HADOOP-11674:
------------------------------------

             Summary: data corruption for parallel CryptoInputStream and CryptoOutputStream
                 Key: HADOOP-11674
                 URL: https://issues.apache.org/jira/browse/HADOOP-11674
             Project: Hadoop Common
          Issue Type: Bug
          Components: io
    Affects Versions: 2.6.0
            Reporter: Sean Busbey
            Assignee: Sean Busbey
            Priority: Critical


A common optimization in the io classes for Input/Output Streams is to save a single length-1 byte array to use in single byte read/write calls.

CryptoInputStream and CryptoOutputStream both attempt to follow this practice but mistakenly mark the array as static. That means that only a single instance of each can be present in a JVM safely.
