Hello, *Context for discussion*:
These classes were recently relocated from "src/main" to "src/test" under HBASE-24115, aligning with the original contributor's initial intention of using them only for testing. Therefore, I'm raising this in an email to initiate discussion with the updated information. At Cloudera, we've noticed a growing adoption of HBase in cloud environments. This shift has highlighted concerns regarding network connectivity requirements between clients and HBase regionservers, particularly for remote clients. To address these concerns, we are looking to utilize standard web protocols such as HTTP. These protocols enable easier integration with various cloud services by providing a single endpoint for access and simplifying networking needs. As a result, more users are interested in using REST servers to meet their requirements. Istvan has put considerable effort into testing and improving the performance of REST servers, as seen in JIRAs like HBASE-28646, HBASE-28613, HBASE-28626, and HBASE-28556 to achieve this target. *Issue*: However, Users with applications currently using the Java client are encountering challenges in transitioning to REST due to the significant code rewriting required. By implementing the Admin and Table interfaces, we can enable these users to migrate to REST with minimal adjustments. *Other Protocol Implementations with Java Public APIs: * Similar interfaces have recently been developed for Thrift under HBASE-21661. *Proposed Changes:* Currently, Istvan focuses on addressing the performance and security aspects of these implementations, with efforts like HBASE-28540 and rewriting Rest Client to support different authentication options, etc. via HBASE-28501,HBASE-28649, and HBASE-28500, which significantly strengthened the implementation. Hence, we want to go ahead and move this implementation back to "src/main". Please inform us of any concerns you may have, otherwise, we would like to proceed with the PR. Regards, Ankit Singhal
