Hive远程模式安装(1.00)

为什么80%的码农都做不了架构师？>>>

hiveserver2和metastore分离部署，元数据存储采用mysql，mysql与metastore分离部署。

mysql: 部署在ctrl节点

hiveserver2: 部署在ctrl和data01节点

metastore: 部署在data02和data03节点

beeline: 部署在其他任意一台机器

部署图：

首先参考《Hive单节点安装使用(1.00)》文档，安装好单节点的hive软件，然后将整个目录拷贝到其他节点，再按如下步骤配置各节点。

安装配置

hiveserver2节点配置

hive 1.0中已经不再提供hiveserver，取而代之的是hiveserver2。
hiveserver2已经不再需要hive.metastore.local这个配置项(hive.metastore.uris为空,则表示是metastore在本地,否则就是远程)，直接配置hive.metastore.uris即可。

<property><name>hive.metastore.uris</name><value>thrift://data02:9083,thrift://data03:9083</value><description>Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.</description>
</property>

hiveserver2不连接mysql数据库，不需要配置连接mysql的配置项。

metastore节点配置

需要配置连接mysql的配置项：

<property><name>javax.jdo.option.ConnectionURL</name><value>jdbc:mysql://ctrl: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 to use against metastore database</description>
</property>
<property><name>javax.jdo.option.ConnectionPassword</name><value>hive</value><description>password to use against metastore database</description>
</property>

其他配置：

hive.metastore.warehouse.dir：hive数据在HDFS中的目录
hive.exec.scratchdir：hive在HDFS中的临时目录
hive.exec.local.scratchdir：hive的本地临时目录，/tmp/hive
hive.downloaded.resources.dir: hive下载的本地临时目录, /tmp/hive

<property><name>hive.metastore.warehouse.dir</name><value>/user/hive/warehouse</value><description>location of default database for the warehouse</description>
</property>
<property><name>hive.exec.scratchdir</name><value>/tmp/hive</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}/< username> is created, with ${hive.scratch.dir.permission}.</description>
</property>
<property><name>hive.exec.local.scratchdir</name><value>/tmp/hive</value><description>Local scratch space for Hive jobs</description>
</property>
<property><name>hive.downloaded.resources.dir</name><value>/tmp/hive</value><description>Temporary local directory for added resources in the remote file system.</description>
</property>

beeline客户端安装

beeline已经集成在hive软件包中，不需要额外安装。下载hive软件包，然后配置hadoop的主目录即可：

cd /opt
wget http://apache.fayea.com/hive/stable/apache-hive-1.0.0-bin.tar.gz
tar -zxvf apache-hive-1.0.0-bin.tar.gz
mv apache-hive-1.0.0-bin hive
cd /opt/hive/conf
mv hive-env.sh.template hive-env.sh

在hive-env.sh中增加：

1
2
3

export HADOOP_HOME=/opt/hadoop/client/hadoop-2.4.1
export HIVE_HOME=/opt/hive
export HIVE_CONF_DIR=/opt/hadoop/client/hive/conf

启动

启动hiveserver2

[hadoop@ctrl bin]$ hive --service hiveserver2 &
[hadoop@data01 bin]$ hive --service hiveserver2 &

或者：

[hadoop@ctrl bin]$ hiveserver2 &
[hadoop@data01 bin]$ hiveserver2 &

启动metastore

[hadoop@data02 bin]$ hive --service metastore &
[hadoop@data03 bin]$ hive --service metastore &

使用beeline连接

[root@cheyo conf]# beeline --color=true --fastConnect=true -u jdbc:hive2://192.168.99.107:10000
[root@cheyo conf]# ../bin/beeline --color=true --fastConnect=true
Beeline version 1.0.0 by Apache Hive
beeline> !connect jdbc:hive2://ctrl:10000

| people       | 27          |
+--------------+-------------+--+
3 rows selected (0.413 seconds)
0: jdbc:hive2://ctrl:10000>

启动hwi(Web界面)

待保/opt/hive/lib/目录下有hive-hwi-1.0.0.war文件。hwi只需要在一台HiveServer2上启动即可。

启动hwi服务

[hadoop@ctrl bin]$ hive --service hwi &

访问Web

http://ip:9999/hwi

注意

使用beeline连接时，填写的username将用于权限管理。填写错误可能会导致运行HiveQL命令时指示没有权限。

日志

Hive的日志默认在/tmp/{username}/hive.log中。可以通过配置文件修改。
比如将日志路径修改为:/opt/hive/log/

cd /opt/hive
mkdir -p /opt/hive/logcd /opt/hive/conf
mv hive-log4j.properties.template hive-log4j.properties
vi hive-log4j.properties
#修改如下一行：
hive.log.dir=/opt/hive/logmv hive-exec-log4j.properties.template hive-exec-log4j.properties
vi hive-exec-log4j.properties
#修改如下一行：
hive.log.dir=/opt/hive/log
