-------------------------------------------

             Summary: Crypto input and output streams implementing Hadoop stream interfaces
                 Key: HADOOP-10603
                 URL: https://issues.apache.org/jira/browse/HADOOP-10603
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: security
            Reporter: Alejandro Abdelnur
            Assignee: Yi Liu


A common set of Crypto Input/Output streams. They would be used by CryptoFileSystem, HDFS
encryption, MapReduce intermediate data and spills. Note we cannot use the JDK Cipher Input/Output
streams directly because we need to support the additional interfaces that the Hadoop FileSystem
streams implement (Seekable, PositionedReadable, ByteBufferReadable, HasFileDescriptor, CanSetDropBehind,
CanSetReadahead, HasEnhancedByteBufferAccess, Syncable, CanSetDropBehind).
