Re: Can’t stop hadoop daemons
Hey Barry, How did you start these daemons in the first place?

Re: Can’t stop hadoop daemons
Sean, One cause I can think of is that your PID directory is on /tmp or so, and the original saved PID files got cleared away by tmpwatch, leading to this state. To fix such a flaw, export HADOOP_PID_DIR in hadoop-env.sh to a more persistent location (such as within HADOOP_HOME/pids itself, say). What version of Hadoop are you using though?
