Hadoop 3: If Hadoop is not installed on your system, then follow the Hadoop 3 installation guide to install and configure Hadoop.

Hadoop MapReduce Project in Java With Eclipse Prerequisites: Let us now start building the Hadoop MapReduce WordCount Project. The article explains the complete steps, including project creation, jar creation, executing application, and browsing the project result.

Example: Classpath when using both Tez and Hadoop archives, set article will provide you the step-by-step guide for creating Hadoop MapReduce Project in Java with Eclipse.

If any archives are specified in, then must be set to define the classpath for these archives as the archive structure is not known.Fragments should not be given to directories or jars. If no fragment is given, the symlink will be set to the name of the archive. In, the text immediately following the ‘#’ symbol is the fragment that refers to the symlink that will be created for the archive.Assuming the steps mentioned so far were followed, set to $/apps/hadoop-x.y.z/hadoop-x.y.#hadoop-mapreduce Set to point to the tar.gz uploaded to HDFS.Hadoop fs -copyFromLocal tez-dist/target/tez-x.y. /apps/tez-x.y.z-SNAPSHOT/

Hadoop fs -mkdir /apps/tez-x.y.z-SNAPSHOT

Assuming that the tez jars are put in /apps/ on HDFS, the command would be.

A tez tarball containing tez and hadoop libraries will be found at tez-dist/target/tez-x.y.

This needs to be done just once after importing the project.Ĭopy the relevant tez tarball into HDFS, and configure tez-site.xml Please build using maven as described above and then use Project Properties to include “target/generatedsources/java” as a source directory into the “Java Build Path” for these projects: tez-api, tez-mapreduce, tez-runtime-internals and tez-runtime-library. Eclipse does not automatically generate Java sources or include the generated sources into the projects.

If you use Eclipse IDE, you can import the projects using “Import/Maven/Existing Maven Projects”.

If you prefer to run the unit tests, remove skipTests from the command above.

has the protobuf-2.5.0 and protobuf-compiler-2.5.0 packages. For rpm-based linux systems, the yum repos may not have the 2.5.0 version.

On Mac OS X with the homebrew package manager brew install protobuf250.Tez also requires Protocol Buffers 2.5.0, including the protoc-compiler.

This assumes that you have already installed JDK8 or later and Maven 3 or later.Build tez using mvn clean package -DskipTests=true =true
