hive安装

ubuntu下面：
（1）安装好java
设置 JAVA_HOME
在文件/etc/profile中设置
JAVA_HOME=/usr/lib/jvm/java-6-sun
export JAVA_HOME

tianzhao@tianzhao-VirtualBox:~/apache/trunk$ echo $JAVA_HOME
/usr/

（2）ssh
tianzhao@tianzhao-VirtualBox:~$ ssh-keygen -t rsa -P ""
tianzhao@tianzhao-VirtualBox:~$ cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys
ssh localhost
如果没有ssh就需要安装
tianzhao@tianzhao-VirtualBox:~$ sudo apt-get install openssh-server
tianzhao@tianzhao-VirtualBox:~$ ssh localhost


（3） hadoop的配置，  hadoop-env.sh  mapred-site.xml hdfs-site.xml core-site.xml
官方的版本里面要在 hadoop-env.sh 加上 ：
export JAVA_HOME=/usr/

tianzhao@tianzhao-VirtualBox:~/hadoop-0.20.2-cdh3u0/conf$ cat core-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->

<configuration>

  <description>The name of the default file system. A URI whose
  scheme and authority determine the FileSystem implementation. The

</property>

<property>
  <name>hadoop.tmp.dir</name>
  <value>/home/tianzhao/hadoop-0.20.2-cdh3u0/tmp</value>
</property>

</configuration>



tianzhao@tianzhao-VirtualBox:~/hadoop-0.20.2-cdh3u0/conf$ cat hdfs-site.xml

<description>The host and port that the MapReduce job tracker runs

</description>
</property>

</configuration>

bin/hadoop namenode -format

bin/start-all.sh
bin/stop-all.sh


（3.1）hbase   hbase-site.xml
<configuration>

  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://localhost:54310/hbase</value>
  </property>

<property>

  </property>

</configuration>

// master
http://localhost:60010
// region server
http://localhost:60030

mysql 4不支持，mysql 5以上才支持。 外键问题。
（4）mysql安装
tianzhao@tianzhao-VirtualBox:~/hive-0.7.0-cdh3u0$ sudo apt-get install mysql-server
root用户密码：tianzhao1234

tianzhao@tianzhao-VirtualBox:~/hive-0.7.0-cdh3u0$ mysql -uroot -ptianzhao1234
mysql> create database hive;
Query OK, 1 row affected (0.00 sec)
mysql> create user 'hive'@'localhost' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'localhost' with grant option;
Query OK, 0 rows affected (0.00 sec)

flush privileges;

sudo /etc/init.d/mysql restart

http://www.pantz.org/software/mysql/mysqlcommands.html




用mysqldump命令行
命令格式
mysqldump -u用户名 -p 数据库名 > 数据库名.sql
范例：
mysqldump -uroot -p abc > abc.sql
（导出数据库abc到abc.sql文件）
提示输入密码时，输入该数据库用户名的密码。

用mysql命令行
命令格式
mysql -u用户名 -p 数据库名 < 数据库名.sql
范例：
mysql -uabc_f -p abc < abc.sql
（导入数据库abc从abc.sql文件）
提示输入密码时，输入该数据库用户名的密码。

drop database hive;
show databases;


（5）hive  hive-config.sh   hive-site.xml
1.修改bin/hive-config.sh
export HADOOP_HOME=/home/tianzhao/hadoop-0.20.2-cdh3u0/

conf/hive-site.xml

tianzhao@tianzhao-VirtualBox:~/hive-0.7.0-cdh3u0/conf$ cat hive-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<!-- Put site-specific property overrides in this file. -->

<configuration>

<property>
  <name>hive.metastore.local</name>
  <value>true</value>
</property>

<property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
        <description>JDBC connect string FOR a JDBC metastore</description>
</property>

<property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
        <description>Driver class name FOR a JDBC metastore</description>
</property>

<property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>hive</value>
        <description>username TOUSE against metastore database</description>
</property>
<property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>123456</value>
        <description>password TOUSE against metastore database</description>
</property>

</configuration>

待修改


export HADOOP_HOME=/home/tianzhao/hadoop-0.19.2
export HADOOP_CONF_DIR=$HOME/config



echo $HOME 
/home/tianzhao
export HIVE_HOME=/home/tianzhao/hive
export HIVE_CONF_DIR=/home/tianzhao/hive-config
export HIVE_LIB=${HIVE_HOME}/lib
export HIVE_AUX_JARS_PATH=/home/tianzhao/jar




在 hive  cli中执行show tables，alter table等hivesql变得很慢，往往是因为mysql的原因，因为hive操作分几部分：表信息操作是通过连接的数据库，目录操作的是hdfs上面的目录，job提交给jobtracker。
show tables主要是从mysql中读取表的信息，然后显示。如果变得很慢就是hive从Mysql获取table信息很慢，可以重启mysql或者把mysql迁移到其他机器上。

hive> show tables;

java.sql.SQLException: Got error 28 from storage engine  这个是因为磁盘空间满了的原因

This issue still exist in MySQL server version 5.1.41
I did a sub-query in FROM clause and used WHERE clause to filter results.
The following query works fine without WHERE clause. If you add WHERE clause you will
receive an error code: "1267 Illegal mix of collations (latin1_swedish_ci, IMPLICIT) and
(utf8_general_ci, COERCIBLE) for operation '='"

This example is taken from the book I was reading:

SELECT PLAYERNO, NAME, PLAYERS.TOWN, NUMBER * 1000
FROM PLAYERS,
(SELECT 'Stratford' AS TOWN, 4 AS NUMBER
UNION
SELECT 'Plymouth', 6
UNION
SELECT 'Inglewood', 1
UNION
SELECT 'Douglas', 2) AS TOWNS
WHERE PLAYERS.TOWN = TOWNS.TOWN
ORDER BY PLAYERNO


脏数据产生了分区字段，然后出错。
