What is MapR?
MapR is one of the Big Data Distribution. It is a complete enterprise distribution for Apache Hadoop which is designed to improve Hadoop’s reliability, performance, and ease of use.
1. High Availability:
MapR provides High Availability features such as Self – Healing it means that no Namenode architecture.
It has job tracker High Availability and NFS. MapR achieves only distributing its file system metadata.
2. Disaster Recovery:
MapR provides mirroring facility which allows users to enable policies and mirror data. It automatically within the multinode cluster or single node cluster between on-premise and cloud infrastructure
MapR is a world record performance cost only $9 to the earlier cost of $5M at a speed of 54 sec. And it handles the large size of clusters like 2,200 nodes.
MapR is the only big data distribution which provides a consistent, point in time recovery because of its unique read and writes storage architecture.
5. Complete Data Protection:
MapR has own security system for data protection in cluster level.
MapR provides automatic behind the scenes compression to data. It applies compression automatically to files in the cluster.
7.Unbiased Open Source:
MapR completely unbiased opensource distribution
8. Real Multitenancy Including YARN also
10. Read and Write file system:
MapR has Read and Write file system.
MapR Ecosystem Packs (MEP):
The “MapR Ecosystem” is the set of open-source that is included in the MapR Platform, and the “pack” means a bundled set of MapR Ecosystem projects with specific versions.
Mostly MapR Ecosystem Packs are released in every quarter and yearly also
A single version of MapR may support multiple MEPs, but only one at a time.
In a familiar case, Hadoop Ecosystem components and Opensource components are like Spark, Hive etc components are included in MapR Ecosystem Packs are like below tools:
Collectd Elasticsearch Grafana Fluentd Kibana Open TSDB
