CentOS6.5下安装Hive2.0.0详解及其报错解决办法

部分摘抄来源于：http://www.centoscn.com/image-text/install/2016/0504/7167.html

本文环境如下： 

操作系统：CentOS6.5 64位 

Hive版本：2.0.0 

JDK版本：1.8.0 64位 

Hadoop版本：2.6.2

1. 所需要的环境

Hive 2.0需要以下运行环境： 

Java 1.7以上（强烈建议使用Java 1.8） 

Hadoop 2.X

2. 下载、解压Hive安装包

Hive官网地址: http://hive.apache.org/ 

例如：

wget "http://mirrors.cnnic.cn/apache/hive/hive-2.0.0/apache-hive-2.0.0-bin.tar.gz"
tar -xzvf apache-hive-2.0.0-bin.tar.gz
mv apache-hive-2.0.0-bin /opt/hive-2.0.0

3. 配置环境变量（可选）

将hive-2.0.0/bin添加到path，以方便访问

vi /etc/profile

在末尾添加：

HIVE_HOME=/opt/hive-2.0.0
PATH=$PATH:$HIVE_HOME/bin

4. 启动单机模式

Hive和Hadoop一样，有3种启动模式，分别是单机模式，伪分布模式，分布模式。这里先来说一下单机模式的启动方式。

4.1 修改配置文件

cd /opt/hive-2.0.0/conf
vi hive-site.xml //也可以用hive-default.xml.template去改，不过这个文件中的配置项太多了

输入以下内容后保存：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
    <name>hive.metastore.warehouse.dir</name>
    <value>/home/hadoop/hive-2.0.0/warehouse</value>
    <description>location of default database for the warehouse</description>
</property>
<property>
   <name>javax.jdo.option.ConnectionURL</name>
   <value>jdbc:derby:/home/hadoop/hive-2.0.0/metastore_db;create=true</value>
   <description>JDBC connect string for a JDBC metastore</description>
</property>
</configuration>

4.2 初始化数据库

schematool -initSchema -dbType derby

出现以下几行说明初始化成功：

[root@master conf]# schematool -initSchema -dbType derby
which: no hbase in (/usr/java/jdk1.8.0/bin:/usr/java/jdk1.8.0/bin:/usr/java/jdk1.8.0/bin:/usr/lib64/qt-3.3/bin:/usr/java/jdk1.8.0/bin:/usr/local/bin:/bin:/usr/bin::/usr/local/sbin:/usr/sbin:/sbin:/home/hadoop/bin:/home/hadoop/hadoop-2.6.2/bin:/home/hadoop/hadoop-2.6.2/sbin:/bin:/home/hadoop/hive-0.12.0:/home/hadoop/hive-2.0.0/bin)

Metastore connection User:     APP
Starting metastore schema initialization to 2.0.0

4.3 启动程序

mkdir -p warehouse       // 创建元数据存储文件夹
chmod a+rwx warehouse    // 修改文件权限
hive

如果出现

hive>

提示符则说明启动成功

Logging initialized using configuration in jar:file:/home/hadoop/hive-2.0.0/lib/hive-common-2.0.0.jar

Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a  spark, tez) or using Hive 1.X releases.

hive> show databases;

ok

default

5. 常见错误

5.1 运行hive时出现

Exception in thread "main" java.lang.RuntimeException: Hive metastore database is not initialized.
Please use schematool (e.g. ./schematool -initSchema -dbType ...) to create the schema. If needed,
don't forget to include the option to auto-create the underlying database in your JDBC connection
string (e.g. ?createDatabaseIfNotExist=true for mysql)

错误原因：  数据库没有初始化，请参照4.2

5.2 使用schematool初始化数据库时出现

Initialization script hive-schema-2.0.0.derby.sql
Error: FUNCTION 'NUCLEUS_ASCII' already exists. (state=X0Y68,code=30000)
org.apache.hadoop.hive.metastore.HiveMetaException: Schema initialization FAILED! Metastore state would be inconsistent !!
*** schemaTool failed ***

错误原因：数据库文件夹中已经存在一些文件，解决方法就是清空数据库文件夹（也就是前面配置的

/opt/hive-2.0.0/metastore_db

文件夹）

5.3运行hive时报错：（部分截图）

[root@master conf]# hive

错误原因：权限问题，百度这个错误：错误信息是说我的root用户没有权限来访问hive中的表信息。

Caused by: org.apache.hadoop.security.AccessControlException: Permission denied: user=root,
access=WR:drwxr-xr-x

error：org.apache.oozie.action.ActionExecutorException: JA002:org.apache.hadoop.security.AccessControlException: Permissiondenied: user=xxj, access=WRITE,inode="user":hadoop:supergroup:rwxr-xr-x

解决办法，到hadoop中去找到配置wenjianhdfs-site.xml

sulution：added this entry to conf/hdfs-site.xml

[hadoop@master hadoop]$ vim hdfs-site.xml

<property>

<name>dfs.permissions</name>

<value>false</value>

</property>

然后再启动就正常了！
