This project contains the source code that accompanies the book Hadoop in Practice, Second Edition.
Apache version 2.0 (for more details look at the license).
The easiest way to start working with the examples is to download a tarball distribution of this project. Doing so will mean that running your first example is just three steps away:
Go to the releases and download the most recent tarball.
Extract the contents ot the tarball.
$ tar -xzvf hip-<version>-package.tar.gz
The examples in the book all use the
hip script located in
execute the examples. While it's not required, it's recommended that you
hip-<version>/bin to your
path so that you can simply execute
hip and execute the examples in the
book by directly copy-pasting the commands.
Run the "hello world" example, which is
$ cd hip-<version> # create two input files in HDFS $ hadoop fs -mkdir -p hip1/input $ echo "cat sat mat" | hadoop fs -put - hip1/input/1.txt $ echo "dog lay mat" | hadoop fs -put - hip1/input/2.txt # run the inverted index example $ ./hip hip.ch1.InvertedIndexJob --input hip1/input --output hip1/output # examine the results in HDFS $ hadoop fs -cat hip1/output/part*
Done! The tarball also includes the sources and JavaDocs.
Here you're going to checkout the trunk and then use Maven to run a build.
Checkout the code.
$ git clone [email protected]:alexholmes/hiped2.git
Build the code and distribution tarball.
$ cd hiped2 $ mvn clean $ mvn validate $ mvn package
The JAR's and tarball will be under the
target directory. Now you can follow the instructions in the
"Tarball" section above to explode the tarball and run an example.
At this point check out the book for more examples and how you can execute them. Or if you find any issues then please go to the issues and open a new issue.
