Hive内嵌模式安装（基于Hadoop）

下载解压到指定目录

（1）配置环境变量 /etc/profile

export HIVE_HOME=/usr/local/hive/

export PATH=$PATH:$HIVE_HOME/bin

（2）修改hive配置文件 hive-env.sh

加入hadoop路径 hive路径 hive的lib路径

#HADOOP_HOME=${bin}/../../hadoop

HADOOP_HOME=/usr/local/hadoop


# HiveConfiguration Directory can be controlled by:
 export HIVE_CONF_DIR=/usr/local/hive/conf


# Foldercontaining extra ibraries required for hive compilation/execution can becontrolled by:
exportHIVE_AUX_JARS_PATH=/usr/local/hive/lib

（3）修改Hive配置文件 hive-site.xml

<property>
   <name>hive.exec.local.scratchdir</name>
   <value>/usr/local/hive/iotmp</value>
    <description>Local scratch space forHive jobs</description>
</property>

<property>
   <name>hive.downloaded.resources.dir</name>
   <value>/usr/local/hive/iotmp/${hive.session.id}_resources</value>
   <description>Temporary localdirectory for added resources in the remote file system.</description>
</property>

<property>
   <name>hive.querylog.location</name>
   <value>/usr/local/hive/iotmp</value>
   <description>Location of Hive runtime structured log file</description>

</property>


<property>
    <name>hive.server2.logging.operation.log.location</name>
    <value>/usr/local/hive/iotmp/operation_logs</value>
    <description>Top level directorywhere operation logs are stored if logging functionality isenabled</description>
</property>

<property>
  <name>javax.jdo.option.ConnectionURL</name>
  <value>jdbc:derby:;databaseName=metastore_db;create=true</value>
  <description>JDBC connect string for aJDBC metastore</description>
</property>



<property>
 <name>javax.jdo.option.ConnectionDriverName</name>
 <value>org.apache.derby.jdbc.EmbeddedDriver</value>
 <description>Driver class name for aJDBC metastore</description>
</property>

（4）修改hive配置文件 hive-config.sh bin目录下

export JAVA_HOME=

export HADOOP_HOME=

export HIVE_HOME=

（5）查看hive-site.xml 搜索关键字HDFS看需要在HDFS上创建哪些目录并创建

（6）初始化hive（先把hadoop启动）

schematool -dbType derby -initSchema

这里可能遇到的坑

原因是根目录下已经有了一个metastore_db，把该文件夹删掉再次执行一下初始化命令即可

如果conf目录下也有metastore_db，那么也删掉

（7）在终端输入hive即可进行hive的命令行

通过运行mysql中的创表和插入语句来判断安装是否成功

create table student(varchar(10));
insert into student values(1);
