Hi, 1. as the message says - address in use. Check with ps if more as one process is running at one time. Stop the node, do ps and kill all processes with flume inside (ps waux|grep flume, if the process are runs as flume you can try killall -9 -u flume) 2. as in the mail before, 0.94 does not work with hadoop-1.0.0 3. the flume master isn't available, or the port is blocked or network issue or something like that
