Let Multiple Jobs Safely Share Your Hadoop Cluster

MapR provides a safe, shared Hadoop environment for multiple jobs, workloads and users. The MapR distribution protects system resources against runaway jobs. MapR assures that no application can inadvertently take resources from the core cluster. In other distributions, a bug in a user job (such as an infinite loop) can bring down the entire cluster.

Safely sharing the cluster also means higher utilization. Setting quotas for users and then tracking capacity usage is made easy whether you are managing one node or thousands.
