------------------------------------
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.
