Thanks Mike and Hari for the response. I am starting fresh so I don't have
to worry about the data. Here is what I did:
1. Deleted the source code
2. Downloaded latest code from trunk
3. Copied flume-conf.properties.template and created flume-conf.properties.
4. Changed the channel type to file. (also commented memoryChannel.capacity
line)
5. Modified log4j.properties to log to console
6. Started using this command: *bin/flume-ng agent -n agent -f
conf/flume-conf.properties -c conf*
6. Got exact same error as before:
[kamal@localhost flume]$ bin/flume-ng agent -n agent -f
conf/flume-conf.properties -c conf
+ exec /usr/local/jdk/bin/java -Xmx20m -cp
'/home/kamal/flume/flume/conf:/home/kamal/flume/flume/lib/*'
-Djava.library.path= org.apache.flume.node.Application -n agent -f
