https://issues.apache.org/jira/browse/Hadoop-6255

1、现在的结构比以前的要稍微复杂一些了，如下：

ziang@v128:~/dev/hadoop-2.0.0-cdh4.0.1$ ls -d */

bin/  cloudera/  etc/  examples/  include/  lib/  libexec/  sbin/  share/  src/

2、外层的启动脚本，都在sbin目录下：

ziang@v128:~/dev/hadoop-2.0.0-cdh4.0.1/sbin$ ls

distribute-exclude.sh         hadoop-setup-conf.sh         httpfs.sh                start-balancer.sh    stop-balancer.sh      update-hdfs-env.sh

hadoop-create-user.sh         hadoop-setup-hdfs.sh         mr-jobhistory-daemon.sh  start-dfs.sh         stop-dfs.sh           yarn-daemon.sh

hadoop-daemon.sh              hadoop-setup-single-node.sh  refresh-namenodes.sh     start-secure-dns.sh  stop-secure-dns.sh    yarn-daemons.sh

hadoop-daemons.sh             hadoop-validate-setup.sh     slaves.sh                start-yarn.sh        stop-yarn.sh

hadoop-setup-applications.sh  hdfs-config.sh               start-all.sh             stop-all.sh          update-hadoop-env.sh

3、内层的被调用脚本，都在bin目录下：

ziang@v128:~/dev/hadoop-2.0.0-cdh4.0.1/bin$ ls

container-executor  hadoop  hdfs  mapred  rcc  yarn

4、Native的so文件都在lib目录下：

ziang@v128:~/dev/hadoop-2.0.0-cdh4.0.1/lib$ ls ./ -R

./:

native

./native:

libhadoop.a   libhadooppipes.a  libhadoop.so.1      libhadooputils.a  libhdfs.la  libhdfs.so.0

libhadoop.la  libhadoop.so      libhadoop.so.1.0.0  libhdfs.a         libhdfs.so  libhdfs.so.0.0.0

5、配置程序文件都放置在libexec

ziang@v128:~/dev/hadoop-2.0.0-cdh4.0.1/libexec$ ls

hadoop-config.sh  hdfs-config.sh  httpfs-config.sh  mapred-config.sh  yarn-config.sh

6、配置文件都在etc目录，对应以前的conf目录

ziang@v128:~/dev/hadoop-2.0.0-cdh4.0.1/etc$ ls ./ -R

./:

hadoop

./hadoop:

core-site.xml               hadoop-metrics.properties  httpfs-log4j.properties  log4j.properties        ssl-server.xml.example

hadoop-env.sh               hdfs-site.xml              httpfs-signature.secret  slaves                  yarn-env.sh

hadoop-metrics2.properties  httpfs-env.sh              httpfs-site.xml          ssl-client.xml.example  yarn-site.xml

7、所有的jar包都在share/hadoop目录下面

          /home/ziang/dev/hadoop-2.0.0-cdh4.0.1/share/hadoop
