在安装hive mysql in hadoop 的时候报了错

bin/hadoop dfsadmin -safemode leave

 

开启调机模式:

cp conf/hive-default.xml.template conf/hive-set.xml

vim conf/hive-set.xml 添加
    <property>
      <name>javax.jdo.option.ConnectionURL</name>

进入mysql 创建帐号:
mysql -uroot -p
grant all privileges on *.* to 'hive'@localhost identified by 'hive';
flush privileges;#刷新权限
set name utf8;
create database hive;#创建数据库

 

 

cd ${HIVE_HOME}/bin

./hive -hiveconf hive.root.logger=DEBUG,console #开启调机模式

hive> show tables;

hive>create table page_view(viewTime int,userid bigint,page_url string,referrer_url string,ip string comment 'IP_Address of the User')comment 'This is the page view table';
