Ubuntu15.04 single/pseudo-distributed installation configuration Hadoop and hive testing machine

Environment

• System: Ubuntu 15.04 32bit
• Hadoop version: hadoop-2.5.2.tar.gz
• JDK version: jdk-8u-45-linux-i586.tar.gz
• Hive Version: apache-hive-0.14.0-bin.tar.gz
• MySQL version: Open-mysql

STEP 1: Installing the JDK

1. Configure the installation JDK, unzip the JDK,

TAR-ZXVF jdk-8u-45-linux-i586.tar.gz/usr/lib/jkd/

2. Re-configure the/etc/profile file

sudo gedit/etc/profile (only with JDK-related parts first)

3. Configure the default JDK versionTo set up our installed JDK as the default JDK version, do the following.
Execute code:

sudo update-alternatives --install /usr/bin/java java  /usr/lib/jdk /jdk1.8.0_45/bin/java 300  

sudo update-alternatives --install /usr/bin/javac javac /usr/lib/ jdk/jdk1.8.0_45/bin/javac 300  

sudo update-alternatives--config java

Test:

Java-version

STEP 2: Install Hadoop

http://dblab.xmu.edu.cn/blog/powerxing/install-hadoop-2-4-1-single-node/

The author introduces it in detail here.

But some issues need to be addressed:

A. If the system restarts Midway Discovery JPS when the Namenode with the Datanode failed to start normally.

workaround: May be due to a reboot, etc. sbin/start-dfs.sh to run it again.

STEP 3: Install Hive

HTTP://WWW.TUICOOL.COM/ARTICLES/BMUJAJJ  

Installation of the problem is not big, step by step solution can be.

But after running the Hive command, run show databases again; Some problems may occur (no database data is displayed) and prompt:

Relative path in absolute URI: ${system:java.io.tmpdir%7d/$%7bsystem:user.name%7d)

This is because the absolute path is not specified in the Hive_home/conf/hive-site.xml file.

Resolved as follows:

A. Create a new Iotmp folder, which is/usr/local/hive/iotmp

B. Replace ${system:java.io.tmpdir}/${system:user.name} with/usr/local/hive/iotmp in document Hive-site.xml

Restart Hive.
