ambari安装的各组件的目录

利用ambari可以快速的搭建Hadoop集群，安装后各组件的默认安装在/usr/hdp/目录下。

[root@hdp-01 2.4.2.0-258]# ls
accumulo  hadoop       hadoop-mapreduce  ranger-hdfs-plugin  spark  zookeeper
etc       hadoop-hdfs  hadoop-yarn       ranger-yarn-plugin  usr

查找方法：

ambari使用rpm包来安装各组件（在本地源目录下可以看到各个组件的包），所以可以通过yum命令进行查找，如下以查找，具体过程如下所示：

[root@hdp-01 ~]# rpm -qa | grep yarn
spark_2_4_2_0_258-yarn-shuffle-1.6.1.2.4.2.0-258.el6.noarch
hadoop_2_4_2_0_258-yarn-2.7.1.2.4.2.0-258.el6.x86_64
ranger_2_4_2_0_258-yarn-plugin-0.5.0.2.4.2.0-258.el6.x86_64

[root@hdp-01 ~]# rpm -ql hadoop_2_4_2_0_258-yarn-2.7.1.2.4.2.0-258.el6.x86_64
/usr/hdp/2.4.2.0-258/etc/hadoop/conf.empty/capacity-scheduler.xml
/usr/hdp/2.4.2.0-258/etc/hadoop/conf.empty/container-executor.cfg
/usr/hdp/2.4.2.0-258/etc/hadoop/conf.empty/yarn-env.sh
/usr/hdp/2.4.2.0-258/etc/hadoop/conf.empty/yarn-site.xml

/usr/hdp/2.4.2.0-258/hadoop-yarn
/usr/hdp/2.4.2.0-258/hadoop-yarn/bin
