> Looking in hadoop-daemon.sh we see the start command redirects logs to the log file by
creating a new file. It does not append to the log.
> nohup nice -n $HADOOP_NICENESS "$HADOOP_HOME"/bin/hadoop --config $HADOOP_CONF_DIR $command
"$@" > "$log" 2>&1 < /dev/null &
> I believe output should be appended to the log file so logrotate copytruncate works.
Currently a large log file cannot be truncated without restarting the running service, which
causes issues in production environments.
> The improved line would be exactly the same, except use >> to open the log file
in append mode.
> nohup nice -n $HADOOP_NICENESS "$HADOOP_HOME"/bin/hadoop --config $HADOOP_CONF_DIR $command
"$@" >> "$log" 2>&1 < /dev/null &
