Apache Slider targets Hadoop environments and is based on the database's next generation MapReduce 2.0 standard, also known as YARN.
Slider can be used to create YARN-compliant applications that interact with the underlying Hadoop database or database cluster, allowing the YARN application to scale up or down based on the needed resources.
Slider also allows developers to monitor the application's processes, keeping track of resource usage and any failures.
If a process fails, Slider will automatically create a new YARN container and try to replace the one that previously failed, minimizing downtime inside Hadoop systems.
Apache Slider runs from the Java CLI and saves all its runtime information inside HDFS as basic JSON files.

- Support a YARN service registry.
What is new in version 0.61.0:
