> 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://s.apache.org/RWU] changed behavior: in 1.4
> includes newlines that break the token file for secure MR configuration
> (ACCUMULO-829).
