MapR is the only solution that provides 99.999% high availability including support for rolling upgrades, self-healing and automated stateful failover.
MapR’s No NameNode HA architecture avoids single points of failure within the system and ensures there are no bottlenecks to cluster scalability. Job Tracker HA feature makes MapR the only distribution to not only restart the job tracker on failure but also continue the current jobs to completion without having to restart them all over again.
MapR also provides dependable data storage with full data protection and business continuity features. MapR Snapshots provide point-in-time recovery to protect against application and user errors. Mirroring across clusters through WAN replication is also uniquely supported by MapR.
MapR provides easy and transparent integration with Kerberos. MapR’s integrated security with native authentication provides users with an alternative out-of-the-box solution for securing Hadoop.
