Db2 Big SQL integration with YARN
YARN is the resource management and scheduling framework for Hadoop. Db2 Big SQL is better integrated with YARN through Apache Slider, which allows services that are not "job-oriented" (and therefore not natively written for YARN) and "long running" services (for example, HBase) to be deployed on YARN.

Using the Db2 Big SQL Slider application with YARN node labels
YARN node labels allow you to group nodes with similar characteristics in order to balance resources and specify where applications run.
Configuring CGroups in YARN
CGroups is a mechanism for aggregating/partitioning sets of tasks, and all their future children, into hierarchical groups with specialized behavior. CGroups is a Linux kernel feature and was merged into kernel version 2.6.24. From a YARN perspective, this allows containers to be limited in their resource usage. A good example of this is CPU usage. Without CGroups, it becomes hard to limit container CPU usage. Currently, CGroups is used only for limiting CPU usage.
