Ubuntu Configuration Hadoop - (IV) Installation Configuration Hive

The first step download Hive
http://archive.apache.org/dist/hive/
them find their favorite versions Download

$ curl -O http://archive.apache.org/dist/hive/hive-3.1.2/apache-hive-3.1.2-bin.tar.gz 
$ tar -xzf apache-hive-3.1.2-bin.tar.gz
$ sudo mv apache-hive-3.1.2-bin /srv/
$ sudo ln -s /srv/apache-hive-3.1.2-bin /srv/hive

The second step, the establishment hive user directory and the default repository directory, as well as to ensure the temporary data can be written hadoop hive directory

$ hadoop fs -mkdir /tmp
$ hadoop fs -mkdir -p /user/hive
$ hadoop fs -mkdir /user/hive/warehouse

$ hadoop fs -chmod g+w /tmp
$ hadoop fs -chmod g+w /user/hive/warehouse

$ chmod g+w /var/app/hadoop/data

The third step is to configure the environment variables

$ sudo su hadoop
$ vim ~/.bashrc

Add the following:

export HIVE_HOME=/srv/hive
export PATH=$PATH:$HIVE_HOME/bin

Enter the following code to validate the configuration saved

$ source ~/.bashrc

The fourth step is to configure hive metastore
use here of the Derby database, only suitable pseudo-distributed mode
we look hive-site.xml configuration file

$ cd $HIVE_HOME/conf
$ sudo cp hive-default.xml.template hive-site.xml
$ vim hive-site.xml

Modify the following several attributes:

<property>
	<name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:derby:;databaseName=/home/hadoop/metastore_db;create=true</value>
</property>
<property>
	<name>hive.exec.scratchdir</name>
	<value>/tmp/hive</value>
</property>
<property>
	<name>hive.exec.local.scratchdir</name>
	<value>/tmp/hive/local</value>
</property>
<property>
	<name>hive.downloaded.resources.dir</name>
	<value>/tmp/hive/resources</value>
</property>

Try to start hive after saving

$ cd $HIVE_HOME
$ bin/hive

If you can see
