1.Hive安裝

1.1下載

官網下載地址apache.fayea.com/hive/，目前最新版為1.2.2，選擇 apache-hive-1.2.2-bin.tar.gz檔案下載。

1.2 配置hive-env.sh

解壓檔案至本地資料夾，進入/conf資料夾，編輯hive-env.sh

# Set HADOOP_HOME to point to a specific hadoop install directory
 HADOOP_HOME=/Users/kk/hadoop/hadoop-2.6.5

# Hive Configuration Directory can be controlled by:
 export HIVE_CONF_DIR=/Users/kk/hadoop/hive-1.2.0/conf

# Folder containing extra ibraries required for hive compilation/execution can be controlled by:
 export HIVE_AUX_JARS_PATH=/Users/kk/hadoop/hive-1.2.0/lib
 

HADOOP_HOME：Hadoop根目錄

HIVE_CONF_DIR：Hive配置資料夾

HIVE_AUX_JARS_PATH：Hive依賴jar包的路徑

1.3 配置hive-site.xml

編輯hive-site.xml檔案，修改以下引數

 <property>
    <name>hive.exec.scratchdir</name>
    <value>/Users/kangkang/hadoop/warehouse</value>
    <description>HDFS root scratch dir for
 
 Hive jobs which gets created with write all (733) permission. For each connecting user, an HDFS scratch dir: ${hive.exec.scratchdir}/&lt;username&gt; is created, with ${hive.scratch.dir.permission}.</description>
  </property>
  <property>
    <name>hive.exec.local.scratchdir</name>
    <value>/Users/kangkang/hadoop/hive-1.2
 
.0/tmp/${user.name}</value>
    <description>Local scratch space for Hive jobs</description>
  </property>
  <property>
    <name>hive.downloaded.resources.dir</name>

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

  ...
  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value>root</value>
    <description>password to use against metastore database</description>
  </property>
  ...
  <property>
    <name>hive.hwi.listen.port</name>
    <value>9999</value>
    <description>This is the port the Hive Web Interface will listen on</description>
  </property>
  ...
  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost:3306/hivedb?createDatabaseIfNotExist=true&amp;useUnicode=true&amp;characterEncoding=UTF-8&amp;useSSL=false</value>
    <description>JDBC connect string for a JDBC metastore</description>
  </property>
  ...
   <property>
    <name>javax.jdo.option.ConnectionDriverName</name>

  </property>
  ...

1.4 新增依賴包

拷貝mysql的驅動jar包(mysql-connector-java-5.1.38.jar)到hive的/lib資料夾

拷貝/hive/lib/jline-2.12.jar 檔案拷貝至 /hadoop-2.6.5/share/hadoop/yarn/lib/下

建立一個快取資料夾/hive-1.2.2/tmp/

2.啟動Hive

在保證本機mysql服務開啟的情況下，啟動Hive命令：

bin/hive
bin/hiveserver2

注意：這裡是兩個服務同時啟動

hiveserver2是啟動服務，為jdbc的訪問提供服務。

3.Hive操作資料

建立表格：

create table table_name(id int primary key, name varchar);

刪除表格：

drop table table_name;

查詢

select * from table_name where id = 1;

Hive匯入檔案內容

load data local inpath '/Users/kk/dim_area.txt' into table dim_area;
