Using the YARN Services API
Previously, deploying a new service on YARN was not a simple experience. The APIs of existing frameworks were either too low level (native YARN), required writing new code (for frameworks with programmatic APIs), or required writing a complex specification (for declarative frameworks). Apache Slider was developed to run services such as HBase, Storm, Accumulo, and Solr on YARN by exposing higher-level APIs that supported running these services on YARN without modification.
The new YARN Services API described in this document greatly simplifies the deployment and management of YARN services.
The YARN Services API helps in creating and managing the life cycle of YARN services.
