    [ https://issues.apache.org/jira/browse/PIG-3194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13580621#comment-13580621 ] 

Jonathan Coveney commented on PIG-3194:
---------------------------------------

Do we want to consider just using commons codec 1.3? Do the newer versions of Hadoop still use that version of commons codec?

> The changes to ObjectSerializer.java in the following commit
> http://svn.apache.org/viewvc?view=revision&revision=1403934 break compatibility with Hadoop 0.20.2 Clusters.
> The reason is, that the code uses methods from Apache Commons Codec 1.4 - which are not available in Apache Commons Codec 1.3 which is shipping with Hadoop 0.20.2.
> The offending methods are Base64.decodeBase64(String) and Base64.encodeBase64URLSafeString(byte[])
> If I revert these changes, Pig 0.11.0 candidate 2 works well with our Hadoop 0.20.2 Clusters.
