Kai Londenberg commented on PIG-3194:
-------------------------------------
I would propose to try and stay as compatible as possible with reasonable
effort. Here, the effort to stay compatible with a still widely used version of
Hadoop seems to be minimal. I see 3 alternative solutions here:
1.) Revert the mentioned commit.
2.) Reproduce the required functionality using code that's compatible to
commons codec 1.3 (i.e. use Base64.decodeBase64(str.getBytes()) instead of the
shortcut Base64.decodeBase64(str).
3.) Embed a rebased commons codec 1.4+ into pig. With that, I mean a version of
commons codec 1.4+ which has been automatically refactored such that it has a
new base package, for example pig.org.apache.commons.codec or something like
that.

> URL: https://issues.apache.org/jira/browse/PIG-3194
> Project: Pig
> Issue Type: Bug
> Reporter: Kai Londenberg

> 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.
