只需要在namenode节点中安装即可
配置环境变量
将如下内容添加到 ~/.bash_profile中
export HIVE_HOME=/root/software/apache-hive-1.2.1-bin
export PATH=$PATH:$HIVE_HOME/bin
拷贝mysql jdbc 包到hive/lib
cp mysql-connector-java-5.1.40-bin.jar $HIVE_HOME/lib
Hive配置
配置hive-env.sh
拷贝hive-env.sh.template到hive-env.sh，添加如下内容：
export HADOOP_HOME=/usr/local/hadoop-2.6.5
export HIVE_CONF_DIR=/root/software/apache-hive-1.2.1-bin/conf
配置hive-site.xml
拷贝hive-default.xml.template到hive-site.xml，将hive-site.xml中ConnectionURL、ConnectionUserName、ConnectionPassword修改为以下内容。
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://192.168.2.180:3306/hive?createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>root</value>
<description>username to use against metastore database</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hunter</value>
<description>password to use against metastore database</description>
</property>
</configuration>
- 将warehouse.dir替换为 /hive/warehouse
- 将local.scratchdir替换为 $HIVE_HOME/exec
- 将downloaded.resources.dir替换为 $HIVE_HOME/downloadedresources
说明：这里使用的mysql已经安装好。
创建配置中的目录
hdfs中的目录
hdfs dfs -mkdir -p /hive/warehouse
hdfs dfs -mkdir -p /hive/log
hdfs dfs -mkdir -p /hive/tmp
本地文件系统中的目录
cd $HIVE_HOME
mkdir log exec downloadedresources
启动hive的matestore
启动hive metastore
hive --service metastore &
停止hive metastore
ps -ef|grep hive|grep -v grep|awk '{print "kill -9", $2}'|sh
进入hive交互CLI
hive
hive> create table t2(id int, name string);
OK
Time taken: 0.104 seconds
hive> show tables;
OK
t2
Time taken: 0.048 seconds, Fetched: 2 row(s)
hive> insert into t2 values(1,'ZhangSan');
错误解决方法
错误1：Hive报错:"/spark//lib/spark-assembly-*.jar: No such file or directory"
问题原因： 新版本的spark,hive没有及时支持更新.
问题解决:
vim $HIVE_HOME/bin/hive
// 定位到位置,上面一行是原有的,下一行是修改的
#sparkAssemblyPath=`ls ${SPARK_HOME}/lib/spark-assembly-*.jar`
sparkAssemblyPath=`ls ${SPARK_HOME}/jars/*.jar`
错误2：FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:For direct MetaStore DB connections, we don't support retries at the client level.
错误原因：数据库的字符集不对，应该是latin1；
解决方法：重建数据库；
