Subject [jira] [Updated] (ACCUMULO-2791) Behavior and binary compatibility mismatch of Commons Codec version provided by Hadoop
Date Sat, 10 May 2014 21:56:49 GMT

     [ https://issues.apache.org/jira/browse/ACCUMULO-2791?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sean Busbey updated ACCUMULO-2791:
----------------------------------

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