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

             Summary: Behavior and binary compatibility mismatch of Commons Codec version
provided by Hadoop
                 Key: ACCUMULO-2791
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2791
             Project: Accumulo
          Issue Type: Bug
          Components: client, docs
    Affects Versions: 1.6.0
            Reporter: Sean Busbey
            Assignee: Sean Busbey
            Priority: Blocker
             Fix For: 1.6.1, 1.7.0


Hadoop 2.x provides commons-codec 1.4. We rely on commons-codec 1.7 in our pom and then rely
on the version from Hadoop for deployment.

This presents two problems:

* VolumeUtil code relies on a method that was added in 1.7, causing the volume migration tool
(ACCUMULO-1832) to fail.
* [encodeBase64String|http://commons.apache.org/proper/commons-codec/archives/1.7/apidocs/org/apache/commons/codec/binary/Base64.html#encodeBase64String(byte[])]
changed behavior: in 1.4 includes newlines that break the token file for secure MR configuration
(ACCUMULO-829).
