Hi,

I need to be able to retrieve the current job id from within map or  
reduce tasks. I looked here and there, but I wasn't able to find  
any way to do this in the API ...

Yes, look under "Localized Properties in the JobConf" on the wiki:

http://wiki.apache.org/lucene-hadoop/TaskExecutionEnvironment

In particular, conf.get("mapred.job.id") and conf.get 
("mapred.task.id") will do the job.
