Difference Between typical Hadoop Architecture and MapR architecture

I know that Hadoop is based on Master/Slave architecture

HDFS works with NameNodes and DataNodes

and MapReduce works with jobtrackers and Tasktrackers

But I can't find all these services on MapR, I find out that it has its own Architecture with its own services

I'm a little bit confused, could any one please tell me what is the difference between using Hadoop only and using it with MapR !

Solution

  • MapR and apache Hadoop DO NOT have same architecture at storage level. MapR uses its own filesystem MaRFS which is completely different from HDFS in terms of concept and implemenation . you can find more detailed comparision here : https://www.mapr.com/blog/comparing-mapr-fs-and-hdfs-nfs-and-snapshots#.VfGwwxG6eUk https://www.mapr.com/resources/videos/comparison-mapr-fs-and-hdfs
