Hello again W.P. McNeill, I'm highly unsure on what form of "Apache Hadoop 0.20.2" version you were running before but looks like you are running into downgraded-like issues by moving onto Apache Hadoop 0.20.203 seeing your recent mails.
IdentifierResolver was part of the major streaming improvement made at https://issues.apache.org/jira/browse/HADOOP-1722 by Klaas, which again, has never gone into 0.20 - but it is in 0.21. Klaas had given patches for branches as old as 0.18, though. I believe this JIRA is one of the requirements to use Dumbo, the python framework @ http://last.fm/dumbo You'll need to patch things to have it back. On Wed, Sep 7, 2011 at 4:57 AM, W.P.
