Running Bigtop Smoke Tests
You can use Bigtop to quickly install a complete stack of Hadoop software if you don't want to use a cluster manager
or a stack-based Hadoop release from one of the major suppliers. Even if you never plan to use Bigtop yourself, it is
worth understanding how it works, because major Hadoop vendors like Cloudera use it.
To execute an Apache Bigtop smoke test as my example, I first install Apache Maven, which is used to build and
run the tests.

■ Note For full details on smoke tests, consult the apache Bigtop website at http://bigtop.apache.org .

I then download the tar and zipped Maven package to /tmp on the server hc2nn by using a wget call to download:

[root@hc2nn tmp]# cd /tmp
[root@hc2nn tmp]# wget http://supergsego.com/apache/maven/maven-3/3.2.3/binaries/apache-maven-
3.2.3-bin.tar.gz

I unzip the package as the root user and unpack it using the tar command:

[root@hc2nn tmp]# gunzip apache-maven-3.2.3-bin.tar.gz
[root@hc2nn tmp]# tar xvf apache-maven-3.2.3-bin.tar

Now, I move the unpacked Maven directory to /usr/local so that it resides in the correct place and create a
generic symbolic link to point to the release, simplifying the configuration:

[root@hc2nn tmp]# mv apache-maven-3.2.3 /usr/local
[root@hc2nn tmp]# cd /usr/local
[root@hc2nn local]# ln -s apache-maven-3.2.3 apache-maven
[root@hc2nn local]# ls -ld apache-maven*
lrwxrwxrwx. 1 root root 18 Aug 30 08:23 apache-maven -> apache-maven-3.2.3
drwxr-xr-x. 6 root root 4096 Aug 30 08:21 apache-maven-3.2.3
