Description

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 changed behavior: in 1.4 includes newlines that break the token file for secure MR configuration (ACCUMULO-829).
