🚧 Ocean Data Discovery with Hadoop

Introduction

Welcome to the underwater world of Hadoop Hive! In this lab, you will take on the role of a marine biologist exploring the depths of data processing with Hadoop's "cluster by Usage" feature. Your mission is to analyze and organize data underwater to better understand the behavior of marine life.

Setting up the Environment

In this step, we will prepare the environment for our data analysis. Follow the instructions below:

1. Create a new directory to store our data:

   mkdir -p /home/hadoop/cluster_by_usage

2. Switch to the Hadoop user:

   su - hadoop

3. Navigate to the new directory:

   cd /home/hadoop/cluster_by_usage

Analyzing Data

In this step, we will analyze the data using the "cluster by Usage" feature of Hadoop Hive. Follow the instructions below:

1. Create a sample dataset file:

   touch /home/hadoop/cluster_by_usage/data.txt

2. Load the data into a Hive table using "cluster by Usage":

   CREATE TABLE analyzed_data
   CLUSTERED BY (column_name) INTO 4 BUCKETS
   AS
   SELECT * FROM data;

Summary

In this lab, we delved into the world of Hadoop Hive and explored the "cluster by Usage" feature to efficiently organize and analyze data. By following the steps in this lab, you have gained hands-on experience in setting up the environment, loading data, and utilizing clustering techniques. Keep exploring and analyzing to uncover hidden insights in your data!
