It is sometimes desirable to run multiple TaskManagers on the same node so we 
cannot simply overwrite the PID file. This situation cannot be prevented after, 
for example, a hard reboot.

In `flink-daemon.sh` the is the following piece of script:
{code}
# Add to pid file if successful start
if [[ ${mypid} =~ ${IS_NUMBER} ]] && kill -0 $mypid > /dev/null 2>&1 ; 
then
echo $mypid >> $pid
else
echo "Error starting $DAEMON daemon."
exit 1
fi
{code}
Could it be changed with {{echo $mypid > $pid}} or it brake something?
