Subject [jira] [Commented] (HADOOP-7228) jar names are not compatible with 0.20.2
Date Thu, 22 Sep 2011 01:20:26 GMT

Eli Collins commented on HADOOP-7228:
-------------------------------------

I patched CDH to preserve the old jar names via symlinks since breaking compatibility wasn't
an option. Can cherry pick it into branch-20-security if you like the fix.

    CLOUDERA-BUILD. Make symlinks so old hadoop jar names are preserved (CDH-1543).

> The jars in 203 are named differently vs. Apache Hadoop 0.20.2.  I understand this was
done to make the Maven people less cranky.  However, this breaks compatibility especially
for streaming users. We need to make sure we have a release note or something significant
so that users aren't taken by surprise.
