Hadoop

In PHP job listings, experience with Hadoop refers to working within a big data ecosystem where PHP applications play a role in data ingestion or consumption. Hadoop is an open-source framework used for distributed storage and processing of large datasets, and while its core is Java-based, PHP developers often build systems that interact with it.

PHP's Interaction with Hadoop

A PHP developer's role in a Hadoop environment is typically not to write MapReduce jobs. Instead, they build applications that either feed data into the Hadoop Distributed File System (HDFS) or query data from it. For example, a high-traffic PHP application might log events that are sent to a data pipeline for processing in Hadoop. Conversely, a PHP-based dashboard might display analytics by querying a data warehouse like Apache Hive, which runs on top of Hadoop, via a REST API.

Relevant Big Data Skills

• Experience designing and consuming REST APIs for data exchange.
• Familiarity with data streaming concepts and tools like Kafka or RabbitMQ.
• Understanding of data warehousing and ETL processes.
• Knowledge of database systems that integrate with Hadoop, such as Hive or HBase.
