Hortonworks（HDP）关闭不须要的组件（服务）

Hortonworks（HDP）设置开机启动的组件（服务）是在一个makefile(.mf)文件里配置的，这个文件位于：

/usr/lib/hue/tools/start_scripts/start_deps.mf

我们仅仅须要改动这一个文件就能够，所以。在此之前。我们最好先做一个备份：

cp /usr/lib/hue/tools/start_scripts/start_deps.mf /usr/lib/hue/tools/start_scripts/start_deps.mf.bak

假设我们想禁止某个组件（服务）在开机时启动，我们仅仅须要找到配置Startup项的那一行代码，通常这一行是这种：

Startup: HDFS YARN Zookeeper Hive_Metastore WebHCat Oozie Falcon Knox

然后删除我们不须要的组件（服务）就可以。比如：假设我们仅仅须要使用HIVE,则能够这样改动，凝视掉现有的行，又一次复制一行，去掉oozie,falcon和knox：

#Startup: HDFS YARN Zookeeper Hive_Metastore WebHCat Oozie Falcon Knox
Startup: HDFS YARN Hive_Metastore WebHCat

另外，假设开启了Ambari, 还将同一时候启动：ganglia和nagios，由于这两项被Ambari所依赖。假设你的机器资源有限，想使用Ambari管理集群又想关闭监控，去除ganglia和nagios开机启动也是能够。作法与上面相似：找到

Ambari: ambari_server ambari_agent ganglia nagios

凝视掉现有的行，又一次复制一行。去掉ganglia nagios：

#Ambari: ambari_server ambari_agent ganglia nagios

Ambari: ambari_server ambari_agent

同一时候，再找到：

ambari_server: ganglia nagios
    $(call colorized,\
        Ambari server, \
        ambari-server start,\
        sleep 5, )

凝视掉第一行，又一次复制一行。去掉ganglia nagios：

#ambari_server: ganglia nagios
ambari_server:    

    $(call colorized,\
        Ambari server, \
        ambari-server start,\
        sleep 5, )
