G o跳转到最后一行

scp -r hadoop-3.3.6 root@node3:$PWD
cd /export/server/hadoop-3.3.6/
cd share/
cd hadoop/
cd mapreduce/
hadoop jar hadoop-mapreduce-examples-3.3.6.jar pi 2 2
ResourceManager :yumn主角色，程序运行找资源
统计单词个数
vim hello.txt
cat hello.txt
hadoop fs -mkdir -p /wordcount/input
hadoop fs -put hello.txt /wordcount/input
cd /export/server/hadoop-3.3.6/share/hadoop/mapreduce/
hadoop jar hadoop-mapreduce-examples-3.3.6.jar wordcount /wordcount/input /wordcount/output

mv zoo_sample.cfg zoo.cfg
ln -s /export/server/apache-zookeeper-3.5.9-bin /export/server/zookeeper
scp -r apache-zookeeper-3.5.9-bin node2:`pwd`/
ln -s /export/server/apache-zookeeper-3.5.9-bin /export/server/zookeeper
/export/server/zookeeper/bin/zkServer.sh
/export/server/zookeeper/bin/zkServer.sh start
tar -zxvf hbase-2.2.2-bin.tar.gz -C /export/server
ln -s /export/server/hbase-2.2.2 /export/server/hbase
hbase集群部署——启动服务界面
bin/start-hbase.sh
bin/stop-hbase.sh
start-all.sh
stop-all.sh
ddl操作表格的list查看表格 drop create
namespace表格命名的 create_namespace list_namespace
dml处理数据的
