> Start scripts should create PIDfiles to store the PID of running processes in a well
known location (example: /var/run/accumulo/tserver.pid or $ACCUMULO_HOME/tserver.pid), for
the following benefits:
> # Identify running services on a machine without executing and parsing the system process
list, so stop scripts can kill them when they are unresponsive.
> # Prevent multiple instances of the same application from starting up (an environment
variable for the location of the PIDfile can be used to allow multiple instances if it is
desirable to do so).
> # Potentially provide an alternate mechanism for terminating a process by deleting its
PIDfile rather than its lock in Zookeeper.
