> hadoop-daemon.sh does not append to log files

> Key: HADOOP-6746

> Project: Hadoop Common

> 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 &
