ОШИБКА: когда запускают hadoop

Я - установленный Hadoop, после учебного руководства noll's Michael. Когда я запускаю узел имени с помощью в качестве после команды,

hduser@ARUL-PC:/usr/local/hadoop$ sbin/start-all.sh

Я получил ответ как,

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

Скажите мне, где я действительно путал...

Когда я проверяю папку конфигурации, я видел ниже,

root@ARUL-PC:/usr/local/hadoop/etc/hadoop# ls
capacity-scheduler.xml  hadoop-metrics2.properties  httpfs-site.xml             ssl-client.xml.example
configuration.xsl       hadoop-metrics.properties   log4j.properties            ssl-server.xml.example
container-executor.cfg  hadoop-policy.xml           mapred-env.cmd              yarn-env.cmd
core-site.xml           hdfs-site.xml               mapred-env.sh               yarn-env.sh
core-site.xml~          hdfs-site.xml~              mapred-queues.xml.template  yarn-site.xml
hadoop-env.cmd          httpfs-env.sh               mapred-site.xml.template
hadoop-env.sh           httpfs-log4j.properties     mapred-site.xml.template~
hadoop-env.sh~          httpfs-signature.secret     slaves

то, что я добавил строки согласно учебному руководству, сказанному в hadoop-env.sh, core-site.xml, для этого файлы, которые другой регистрирует, автоматически создали окончание '~' как то же как имя файла. Это нормально, или это - проблема?

Я открываю тот файл с помощью 'gedit' как,

root@ARUL-PC:/usr/local/hadoop/etc/hadoop# gedit hadoop-env.sh~

Я вижу,

Как разрешить эту проблему.
