Apache Knox provides a centralized spot in a Hadoop-based cluster, where various queries are aggregated and sent to the servers.
This gateway can be used to avoid duplicate queries running in the system, but also for securing the platform against unauthorized access or by implementing auditing and performance boosting systems.
By having just one single point that handles all the queries, developers are in full control of what goes in the Hadoop clusters and are able to handle query input and output streams, avoiding traffic spikes or server failures.
This also modularizes and improves overall safety for the entire architecture, by controlling traffic, authentication, and also masking various cluster services and ports.
Requirements:
- Java 1.6 or higher
