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.
Why MapR?
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
3.Record Performance:
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.
4.Consistent Snapshots:
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.
6.Compression:
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
9.Enterprise-grade NoSQL
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
