1）修改hdfs配置 hdfs配置位置：/etc/hadoop/conf

同步hdfs配置

cat /home/hadoop/slaves|xargs -i -t scp /etc/hadoop/conf/hdfs-site.xml hadoop@{}:/etc/hadoop/conf/hdfs-site.xml #关闭： cat /home/hadoop/slaves|xargs -i -t ssh hadoop@{} "sudo /home/hadoop/cdh4/hadoop-2.0.0-cdh4.2.1/sbin/hadoop-daemon.sh --config /etc/hadoop/conf stop datanode" #启动： cat /home/hadoop/slaves|xargs -i -t ssh hadoop@{} "sudo /home/hadoop/cdh4/hadoop-2.0.0-cdh4.2.1/sbin/hadoop-daemon.sh --config /etc/hadoop/conf start datanode"

2）修改hbase配置 hbase配置位置：/home/hadoop/hbase

同步hbase配置

cat /home/hadoop/hbase/conf/regionservers|xargs -i -t scp /home/hadoop/hbase/conf/hbase-site.xml hadoop@{}:/home/hadoop/hbase/conf/hbase-site.xml

graceful重启

cd ~/hbase bin/graceful_stop.sh --restart --reload --debug inspurXXX.xxx.xxx.org

hbase shell 脚本

编写一个文本文件hbasedemo.txt： disable 'table1' drop 'table1' create 'table1', 'column_family1','column_family2' list 'table1' put 'table1', 'row_key1', 'column_family1:col1', 'value1' put 'table1', 'row_key2', 'column_family1:col2', 'value2' put 'table1', 'row_key3', 'column_family2:col3', 'value3' put 'table1', 'row_key4', 'column_family2:col4', 'value4' scan 'table1' scan 'table1',{LIMIT=>5} get 'table1', 'row_key1' get 'table1','row_key1', 'column_family1:col1' count 'table1'

disable 'table1' alter 'table1',NAME=>'column_family3' alter 'table1','delete'=>'column_family3' enable 'table1' describe 'table1' grant 'root','RW','table1' user_permission 'table1'

delete 'table1','row_key1','column_family1:col1' deleteall 'table1','row_key1' truncate 'table1'

在HBase shell中运行这个脚本 hbase shell hbasedemo.txt
