Hive1.2.1安裝配置

一、前提

-安裝好 hadoop集羣
-安裝好 mysql

二、配置

-配置環境變量

-配置bin下hive-config.sh

export JAVA_HOME=/usr/local/spark/jdk1.8.0_73
export HADOOP_HOME=/usr/local/spark/hadoop-2.6.0
export HIVE_HOME=/usr/local/spark/apache-hive-1.2.1-bin

-配置 conf 下的 hive-site.xml

<configuration>
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://master:3306/hive?createDatabaseInfoNotExist=true</value> 
    </property>

    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>root</value>
    </property>

    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>123456</value>
    </property>

    <property>
        <name>hive.metastore.warehouse.dir</name>
        <value>/user/hive/warehouse</value>
    </property>

</configuration>

注：
1.mysql中需要提前建數據庫 hive 不然會報錯
2.安裝過程可能會報以下錯

[ERROR] Terminal initialization failed; falling back to unsupported
java.lang.IncompatibleClassChangeError: Found class jline.Terminal, but interface was expected
原因： 
hadoop目錄下存在老版本jline： 
/hadoop-2.6.0/share/hadoop/yarn/lib： 
-rw-r--r-- 1 root root   87325 Mar 10 18:10 jline-0.9.94.jar 
解決： 
cp /hive/apache-hive-1.1.0-bin/lib/jline-2.12.jar /hadoop-2.5.2/share/hadoop/yarn/lib 

三、操作

運行 hive進行shell模式

建表

create table employee(id int, name String, salary double, country String) Row Format delimited fields terminated by '\|' lines terminated by '\n';

導入數據

load data local inpath "/usr/local/spark/apache-hive-1.2.1-bin/examples/files/employee_part.txt" into table employee;

overwrite 模式導入數據

load data local inpath "/usr/local/spark/apache-hive-1.2.1-bin/examples/files/employee_part.txt" overwrite into table employee;

查詢表

select * from employee;

進入 hdfs查看數據
