# 单独部署新的yarn

由于biginsights整了一套的环境变量，在加载profile的时刻就会进行初始化。所以需要搞一个新的用户在加载用户的环境变量的时刻把这些值清理掉。同时也为了与原来的有所区分。

[esw@bigdatamgr1 ~]$ cat .bash_profile 
...
for i in ~/conf/*.sh ; do
  if [ -r "$i" ] ; then
    . "$i"
  fi
done

[esw@bigdatamgr1 ~]$ ll conf/

-rwxr-xr-x 1 esw biadmin 292 Mar 24 20:48 reset-biginsights-env.sh

使用biadmin停掉原来的jobtracker-tasktracker。

[biadmin@bigdatamgr1 IHC]$ ssh `hdfs getconf -confKey mapreduce.jobtracker.address | sed 's/:.*//' ` "sudo -u mapred /data/opt/ibm/biginsights/IHC/sbin/hadoop-daemon.sh  stop jobtracker"

[biadmin@bigdatamgr1 biginsights]$ for h in `cat hadoop-conf/slaves ` ; do ssh $h "sudo -u mapred /data/opt/ibm/biginsights/IHC/sbin/hadoop-daemon.sh  stop tasktracker" ; done

这里使用while不行，不知道为啥!?

部署新的hadoop-2.2.0。使用超级管理员新建目录给esw用户：

usermod -g biadmin esw
mkdir /data/opt/ibm/biginsights/hadoop-2.2.0
chown esw:biadmin hadoop-2.2.0

使用超级管理员同步到各个slaver节点：

[root@bigdatamgr1 biginsights]# for line in `cat hadoop-conf/slaves` ; do ssh $line "usermod -g biadmin esw" ; done

[root@bigdatamgr1 biginsights]# cat hadoop-conf/slaves | while read line ; do rsync -vazXog hadoop-2.2.0 $line:/data/opt/ibm/biginsights/ ; done

把属性配置好（hdfs，slaves可以用原来的就建立一个软链即可），然后用sbin/start-yarn.sh启动即可。

# 其他命令

[esw@bigdatamgr1 hadoop-2.2.0]$ for line in `cat etc/hadoop/slaves` ; do echo "================$line" ; ssh $line "top -u esw -n 1 -b | grep java | xargs -I{}  kill {} "   ; done

# 部署值得鉴戒学习的IBM bigsql套件：

• 一个管理用户部署，各个引用使用各自的用户

[root@bigdatamgr1 ~]# cat /etc/sudoers

启用时管理员用户使用sudo -u XXX COMMAND操作。

• 所有应用部署/启动管理

[biadmin@bigdatamgr1 biginsights]$ bin/start.sh -h
Usage: start.sh <component>...
    Start one or more BigInsights components. Start all components if 'all' is
    specified. If a component is already started, this command does nothing to it.
    
    For example:
        start.sh all
          - Starts all components.
        start.sh hadoop zookeeper
          - Starts hadoop and zookeeper daemons.

OPTIONS:
    -ex=<component>
        Exclude a component, often used together with 'all'. I.e. 
        `stop.sh all -ex=console` stops all components but the mgmt console.

    -h, --help
        Get help information.

• 反复依赖的包，通过软链来管理
