URL: https://issues.apache.org/jira/browse/HDFS-2715
Project: Hadoop HDFS
Issue Type: Bug
Components: scripts

The sbin script pid detection is broken. Running star-dfs.sh indicates the
following even if there are no processes are running and the pid dir is empty
before starting.
{noformat}
hadoop-0.24.0-SNAPSHOT $ ./sbin/start-dfs.sh
Starting namenodes on [localhost localhost]
localhost: starting namenode, logging to
/home/eli/hadoop/dirs1/logs/eli/hadoop-eli-namenode-eli-thinkpad.out
localhost: namenode running as process 25256. Stop it first.
