A lovely feature of Solaris is that your global zone may host both a Hadoop cluster set up in a manner similar to Orgad's instructions and simultaneously host a zone for development that is running a Hadoop standalone configuration.
Create the ZoneThese instructions assume that Solaris 11.1 is already running in the Global Zone.
Add the Hadoop Studio Zone
# dladm create-vnic -l net0 hadoop_studio
# zonecfg -z hadoop-studio
Use 'create' to begin configuring a new zone.
create: Using system default template 'SYSdefault'
zonecfg:hadoop-studio> set zonepath=/ZONES/hadoop-studio
zonecfg:hadoop-studio> add net
zonecfg:hadoop-studio:net> set physical=hadoop_studio
Install and boot the zone
# zoneadm -z hadoop-studio install
# zoneadm -z hadoop-studio boot
Login to the zone console to set the network, time, root password, and unprivileged user.
# zlogin -C hadoop-studio
After the zone's initial configuration steps, nothing else needs to be done from within the global zone. You should be able to log into the Hadoop Studio zone with ssh as the unprivileged user and gain privileges with "su" and "sudo".
All of the remaining instructions are from inside the Hadoop Studio Zone.
Install extra Solaris software and set up the development environment
I like to start with both JDK's installed and not rely on the "/usr/java" symbolic link:
# pkg install jdk-6
# pkg install --accept jdk-7
Verify the JDKs:
# /usr/jdk/instances/jdk1.6.0/bin/java -version
java version "1.6.0_35"
Java(TM) SE Runtime Environment (build 1.6.0_35-b10)
Java HotSpot(TM) Server VM (build 20.10-b01, mixed mode)
# /usr/jdk/instances/jdk1.7.0/bin/java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) Server VM (build 23.3-b01, mixed mode)
Add VNC Remote Desktop software
# pkg install --accept solaris-desktop
Create a Hadoop user:
# groupadd hadoop
# useradd -d localhost:/export/home/hadoop -m -g hadoop hadoop
# passwd hadoop
# usermod -R root hadoop
export PAGER="/usr/bin/less -ins"
typeset +x PS1="\u@\h:\w\\$ "
alias solstudio='solstudio --jdkhome /usr/jdk/instances/jdk1.6.0'
And make sure that the ownership and permission make sense:
# ls -l /home/hadoop/.bash*
-rw-r--r-- 1 hadoop hadoop 12 May 22 05:24 /home/hadoop/.bash_profile
-rw-r--r-- 1 hadoop hadoop 372 May 22 05:24 /home/hadoop/.bashrc
Now is a good time to a start remote VNC desktop for this zone:
# su - hadoop
You will require a password to access your desktops.
xauth: file /home/hadoop/.Xauthority does not exist
New 'hadoop-studio:1 ()' desktop is hadoop-studio:1
Creating default startup script /home/hadoop/.vnc/xstartup
Starting applications specified in /home/hadoop/.vnc/xstartup
Log file is /home/hadoop/.vnc/hadoop-studio:1.log
Access the remote desktop with your favorite VNC client
The default 10 minute time out on the VNC desktop is too fast for my preferences:
System -> Preferences -> Screensaver
Blank after: 100
Close the window (I always look for a "save" button, but no, just close the window without explicitly saving.)
Download and Install HadoopFor this article, I used the "12 October, 2012 Release 1.0.4" release. Download the Hadoop tarball and copy it into the home directory of hadoop:
$ ls -l hadoop-1.0.4.tar.gz
-rw-r--r-- 1 hadoop hadoop 62793050 May 21 12:03 hadoop-1.0.4.tar.gz
Unpack the tarball into the home directory of the hadoop user:
$ gzip -dc hadoop-1.0.4.tar.gz | tar -xvf -
$ mv hadoop-1.0.4 hadoop
Hadoop comes pre-configured in Standalone ModeEdit /home/hadoop/hadoop/conf/hadoop-env.sh, and set JAVA_HOME:
That is all. Now, you can run a Hadoop example:
$ hadoop jar hadoop/hadoop-examples-1.0.4.jar pi 2 10
Number of Maps = 2
Samples per Map = 10
Wrote input for Map #0
Wrote input for Map #1
Job Finished in 10.359 seconds
Estimated value of Pi is 3.80000000000000000000
Install Solaris Studio:
Visit https://pkg-register.oracle.com/ to obtain
Oracle_Solaris_Studio_Support.certificate.pem and follow the
instructions for "pkg set-publisher" and "pkg update" or "pkg
# sudo pkg set-publisher \
-k /var/pkg/ssl/Oracle_Solaris_Studio_Support.key.pem \
-c /var/pkg/ssl/Oracle_Solaris_Studio_Support.certificate.pem \
-G '*' -g https://pkg.oracle.com/solarisstudio/support solarisstudio
# pkg install developer/solarisstudio-123/*
If your network requires a proxy, you will need set the proxy before starting Solaris Studio:
Start Solaris Studio:
(Notice the alias in .bashrc that adds --jdkhome to the solstudio start up command.)
Go to "Tools -> Plugins.
Click on "Reload Catalog"
Load the Java SE plugins. I ran into a problem when the Maven plug in was installed. Something that I should diagnose at a future date.
Create a New Project:
File -> New Project
- Catagory: Java
- Project: Java Application
Step 2: Fill in similar to this:
Copy the example source into the project:
$ cp -r \
Starting to look like a development environment:
Modify the Project to compile with Hadoop jars. Right-click on the project and select "Properties"
Add in the necessary Hadoop compile jars:
I found that I needed these jars at run time:
Add Program Arguments (2 10):
Now, if you click on the "Run" button. PiEstimators will run inside the IDE:
And the set up behaves as expected if you set a break point and click on "Debug":
