I specify a class at runtime via a parameter to a job. I used to put a
jar with the possible class choices in $HADOOP_HOME/lib on all machines
(using only one in a psuedo cluster for this example) then restart my
cluster and run my job. Then I upgraded from 0.20.203 to 0.20.205, which
may have nothing to do with the problem but there it is.
In any case the job cannot find the class in $HADOOP_HOME/lib. I checked
the jar and its in the right place and has my classes in it.
Did I miss something? Is there a better way?
Sorry ahead of time, this must be a repeat of a repeat but the above is
the best advice I can find.
