You need to copy hadoop-core-x.x.x.jar to ${flume_home}/lib directory.
This file can be found under your hadoop home directory.
e.g.
hadoop 1.0.4 installed in "/home/hadoop/hadoop-1.0.4"
hadoop-core-1.0.4.jar is in this directory.
cp /home/hadoop/hadoop-1.0.4/hadoop-core-1.0.4.ja ${flume_home}/lib should be able to resolve this problem.
Thanks, Hi had this same problem.And it goes once i copy the hadoop-core.jar file.
