我在我的ubuntu12.04中安装了hadoop，方法是按照下面链接中的步骤。
http://www.bogotobogo.com/hadoop/bigdata_hadoop_install_on_ubuntu_single_node_cluster.php
一切都安装成功，当我运行start-all.sh时，只有一些服务正在运行。

wanderer@wanderer-Lenovo-IdeaPad-S510p:~$ su - hduse
Password:

hduse@wanderer-Lenovo-IdeaPad-S510p:~$ cd /usr/local/hadoop/sbin

hduse@wanderer-Lenovo-IdeaPad-S510p:/usr/local/hadoop/sbin$ start-all.sh

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [localhost]

hduse@wanderer-Lenovo-IdeaPad-S510p:/usr/local/hadoop/sbin$ jps
7940 Jps
7545 ResourceManager
7885 NodeManager

一旦我通过运行脚本stop-all.sh停止服务

hduse@wanderer-Lenovo-IdeaPad-S510p:/usr/local/hadoop/sbin$ stop-all.sh
This script is Deprecated. Instead use stop-dfs.sh and stop-yarn.sh
Stopping namenodes on [localhost]
hduse@localhost's password:

hduse@0.0.0.0's password:

我是hadoop新手，找不到问题。在哪里可以找到jobtracker和namenode的日志文件以跟踪服务？
