Apache Hadoop Ozone. Ozone is a scalable, redundant, and distributed object store for Hadoop. Apart from scaling to billions of objects of varying sizes, Ozone can function effectively in containerized environments like Kubernetes. Applications like Apache Spark, Hive and YARN, work without any modifications when using Ozone. If you wish to configure the Connector that is used for connections to web servers using the WARP protocol (such as the modwebapp connector for Apache 1.3), see here instead. At server startup time, this Connector will create a number of request processing threads (based on the value configured for the minProcessors attribute).
Apache Axis2™ is a Web Services / SOAP / WSDL engine, the successor to thewidely used Apache Axis SOAP stack.There are two implementationsof the Apache Axis2 Web services engine - Apache Axis2/Java andApache Axis2/C
While you will find all the information on Apache Axis2/Javahere, you can visit the Apache Axis2/CWeb site for Axis2/C implementation information.

Why Apache Axis2:
A new architecture for Axis2 was introduced during the August2004 Summit in Colombo, Sri Lanka. The new architecture on whichAxis2 is based on is more flexible, efficient and configurable incomparison to Axis1.xarchitecture. Some well established concepts from Axis 1.x,like handlers etc., have been preserved in the newarchitecture.
Apache Axis2 not only supports SOAP 1.1 and SOAP 1.2, but italso has integrated support for the widely popular REST style of Webservices. The same business logic implementation can offer botha WS-* style interface as well as a REST/POX style interfacesimultaneously.
Apache Axis2 is more efficient, more modular and moreXML-oriented than the older version. It is carefully designed tosupport the easy addition of plug-in 'modules' that extend theirfunctionality for features such as security and reliability. TheModulescurrently available or under development include:
- WS-Security - Supported by Apache Rampart
- WS-Addressing -Module included as part of Axis2core
Apache Disable Http 1.0
Apache Axis2 is built on Apache AXIOM, anew high performant, pull-based XML object model.
Apache Http 1.0 Password
Axis2 comes with many new features, enhancements and industryspecification implementations. The key features offered are asfollows:
Speed - Axis2 usesits own object model and StAX (Streaming API for XML) parsing toachieve significantly greater speed than earlier versions of ApacheAxis.
Low memory footprint- Axis2 was designed ground-up keeping low memoryfoot print in mind.
AXIOM - Axis2 comeswith its own light-weight object model, AXIOM, for messageprocessing which is extensible, highly performant and is developerconvenient.
Hot Deployment - Axis2 is equippedwith the capability of deploying Web services and handlers whilethe system is up and running. In other words, new services can beadded to the system without having to shut down the server. Simplydrop the required Web service archive into the services directoryin the repository, and the deployment model will automaticallydeploy the service and make it available for use.
Asynchronous Webservices - Axis2 now supports asynchronous Web servicesand asynchronous Web services invocation using non-blocking clientsand transports.
MEP Support - Axis2now comes handy with the flexibility to support Message ExchangePatterns (MEPs) with in-built support for basic MEPs defined inWSDL 2.0.
Flexibility - TheAxis2 architecture gives the developer complete freedom to insertextensions into the engine for custom header processing, systemmanagement, and anything else you can imagine.
Stability - Axis2defines a set of published interfaces which change relativelyslowly compared to the rest of Axis.
Component-orientedDeployment - You can easily define reusable networks ofHandlers to implement common patterns of processing for yourapplications, or to distribute to partners.
Transport Framework- We have a clean and simple abstraction for integrating and usingTransports (i.e., senders and listeners for SOAP over variousprotocols such as SMTP, FTP, message-oriented middleware, etc), andthe core of the engine is completely transport-independent.
WSDL support - Axis2supports the Web Service Description Language, version 1.1 and 2.0, which allows you to easilybuild stubs to access remote services, and also to automaticallyexport machine-readable descriptions of your deployed services fromAxis2.
Composition andExtensibility - Modules and phases improve support forcomposability and extensibility. Modules support composability andcan also support new WS-* specifications in a simple and cleanmanner. They are however not hotdeployable as they change the overall behavior of thesystem.
