Hadoop单机模式中Hive安装配置

来源:互联网 发布:浮雕设计软件 编辑:程序博客网 时间:2024/06/09 12:05

本文主要是演示在Hadoop单机模式中Hive默认(嵌入式derby 模式)安装配置过程,目录结构如下:

  • 基础环境
  • Hive安装配置
  • 启动及演示

[一]、基础环境

  • Mac OSX 10.9.1
  • Java 1.6+ 
  • Hadoop 2.2.0 (安装配置详见: http://www.micmiu.com/opensource/hadoop/hadoop2x-single-node-setup/  )
  • Hive 0.12.0 (截止2014-02-09最新的发布版本)

[二]、Hive安装配置

1、下载发布包

到官方下载最近发布包以 0.12.0为例:

$ tar -zxf hive-0.12.0-bin.tar.gz -C /usr/local/share $ cd /usr/local/share$ ln -s hive-0.12.0-bin hive

本文中 HIVE_HOME = “/usr/local/share/”

2、设置环境变量

执行 vi ~/.profile  ,添加如下内容:

#Hive @micmiu.comexport HIVE_HOME="/usr/local/share/hive"export PATH=$HIVE_HOME/bin:$PATH

3、配置文件

在目录 <HIVE_HOME>/conf 目录下有4个模板文件:

hive-default.xml.templatehive-env.sh.templatehive-exec-log4j.properties.templatehive-log4j.properties.template

copy 生成四个配置文件然后既可自定义相关属性:

$ cd  /usr/local/share/hive/conf$ copy hive-default.xml.template hive-site.xml$ copy hive-env.sh.template hive-env.sh$ copy hive-exec-log4j.properties.template hive-exec-log4j.properties$ copy hive-log4j.properties.template hive-log4j.properties

ps:注意文件名称: hive-site.xml ,本文以嵌入式derby 模式做演示,故以默认配置即可无效修改相关参数。

不过官方0.12.0的发布版本中的 hive-default.xml.template 中有 bug,在 2000行:

<value>auth</auth>  修改为: <value>auth</value>

有关 hive.metastore.schema.verification 版本检查的问题,有两个解决办法

方法一: 修改配置文件

第一次运行前先将 hive.metastore.schema.verification 设为false

......<!-- 设为false 不做验证--><name>hive.metastore.schema.verification</name><value>false</value>......

方法二: 不改配置,先初始化好数据

执行初始化命令: schematool -dbType derby -initSchema

micmiu-mbp:~ micmiu$ schematool -dbType derby -initSchemaMetastore connection URL: jdbc:derby:;databaseName=metastore_db;create=trueMetastore Connection Driver : org.apache.derby.jdbc.EmbeddedDriverMetastore connection User: APPStarting metastore schema initialization to 0.12.0Initialization script hive-schema-0.12.0.derby.sqlInitialization script completedschemaTool completeted

查看初始化后的信息:  schematool -dbType derby -info

micmiu-mbp:~ micmiu$ schematool -dbType derby -infoMetastore connection URL: jdbc:derby:;databaseName=metastore_db;create=trueMetastore Connection Driver : org.apache.derby.jdbc.EmbeddedDriverMetastore connection User: APPHive distribution version: 0.12.0Metastore schema version: 0.12.0schemaTool completeted

详见: https://cwiki.apache.org/confluence/display/Hive/Hive+Schema+Tool

以上方法都可以,否则第一次运行时会类似如下的报错信息:

ERROR exec.DDLTask (DDLTask.java:execute(435)) - org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient        at org.apache.hadoop.hive.ql.metadata.Hive.getDatabase(Hive.java:1143)        ......Caused by: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient        at org.apache.hadoop.hive.metastore.MetaStoreUtils.newInstance(MetaStoreUtils.java:1212)        ......Caused by: java.lang.reflect.InvocationTargetException        ......Caused by: MetaException(message:Version information not found in metastore. )        at org.apache.hadoop.hive.metastore.ObjectStore.checkSchema(ObjectStore.java:5638)        at org.apache.hadoop.hive.metastore.ObjectStore.verifySchema(ObjectStore.java:5622)        ......

4、配置dfs中得目录和权限

$ hdfs dfs -mkdir       /tmp$ hdfs dfs -mkdir       /user/hive/warehouse$ hdfs dfs -chmod g+w   /tmp$ hdfs dfs -chmod g+w   /user/hive/warehouse

[三]、运行和测试

确保 HADOOP_HOME 在环境变量中配置好,然后以CLI(command line interface)方式下运行,直接执行命令  hive 即可,然后执行一些测试命令如下:

hive> show databases;OKdefaultTime taken: 4.966 seconds, Fetched: 1 row(s)hive> show tables;OKTime taken: 0.186 secondshive> CREATE TABLE micmiu_blog (id INT, siteurl STRING);OKTime taken: 0.359 secondshive> SHOW TABLES;OKmicmiu_blogTime taken: 0.023 seconds, Fetched: 1 row(s)hive>

到此嵌入式derby 模式下的Hive安装配置已经成功。

安装错误

[root@bogon bin]# schematool -dbType derby -initSchema
Metastore connection URL: jdbc:derby:;databaseName=metastore_db;create=true
Metastore Connection Driver : org.apache.derby.jdbc.EmbeddedDriver
Metastore connection User: APP
Starting metastore schema initialization to 1.2.0
Initialization script hive-schema-1.2.0.derby.sql
[ERROR] Terminal initialization failed; falling back to unsupported
java.lang.IncompatibleClassChangeError: Found class jline.Terminal, but interface was expected

Exception in thread "main" java.lang.IncompatibleClassChangeError: Found class jline.Terminal, but interface was expected

at org.apache.hive.beeline.BeeLine.<init>(BeeLine.java:117)
解决办法

条件:hive1.2.1

hadoop2.6.0

原因:

hadoop目录下存在老版本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

解决:

cp /hive/apache-hive-1.1.0-bin/lib/jline-2.12.jar /hadoop-2.5.2/share/hadoop/yarn/lib


错误二

Exception in thread "main"java.lang.RuntimeException: java.lang.IllegalArgumentException:java.net.URISyntaxException: Relative path in absolute URI:${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D
        atorg.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:444)
        atorg.apache.hadoop.hive.cli.CliDriver.run(CliDriver.java:672)

解决办法:

1.查看hive-site.xml配置,会看到配置值含有"system:java.io.tmpdir"的配置项
2.
新建文件夹/home/grid/hive-0.14.0-bin/iotmp
3.将含有"system:java.io.tmpdir"的配置项的值修改为如上地址
启动hive,成功!
