Why is the main difference between Hadoop V1 and v2?
Why is the main difference between Hadoop V1 and v2?
In Hadoop 1, there is HDFS which is used for storage and top of it, Map Reduce which works as Resource Management as well as Data Processing. In Hadoop 2, there is again HDFS which is again used for storage and on the top of HDFS, there is YARN which works as Resource Management.
What is difference between Cloudera and Hadoop?
Cloudera Distribution Hadoop (CDH) has the ability to add new services to a running Hadoop cluster as well as it supports multi cluster management….Difference between Cloudera and MapR :
| S.No. | CLOUDERA | MAPR |
|---|---|---|
| 11. | It runs on Hadoop Distributed File System (HDFS). | MAPR runs on MapR File System (MAPRFS). |
What are the differences between Hadoop 2 and Hadoop 3?
Hadoop cannot cache the data in memory. Hadoop 3 can work up to 30% faster than Hadoop 2 due to the addition of native Java implementation of the map output collector to the MapReduce. Spark can process the information in memory 100 times faster than Hadoop. If working with a disk, Spark is 10 times faster than Hadoop.
What are the different versions of Hadoop?
Below are the two Hadoop Versions: Hadoop 1. x (Version 1) Hadoop 2 (Version 2)…Version 3
- It has now improved feature work on the container concept which enables had to perform generic which were earlier not possible with version 1.
- The latest version 3.2.
What is the difference between MapReduce 1 and 2?
MapReduce in Hadoop 2 was split into two components. The cluster resource management capabilities became YARN (Yet Another Resource Negotiator), while the MapReduce-specific capabilities remained MapReduce. In the MapReduce version 1 (MRv1) architecture, the cluster was managed by a service called the JobTracker.
What is difference between flume and sqoop?
Sqoop is used for bulk transfer of data between Hadoop and relational databases and supports both import and export of data. Flume is used for collecting and transferring large quantities of data to a centralized data store.
How is cloudera different?

Does MapReduce 1.0 include YARN?
Basically, Map-Reduce 1.0 was split into two big components – YARN and MapReduce 2.0. YARN is only responsible for managing and negotiating resources on cluster and MapReduce 2.0 has only the computation framework also called workfload which run the logic into two parts – map and reduce.
What is the difference between MR1 in Hadoop 1.0 and MR2 in hadoop2 0?
The Difference between MR1 and MR2 are as follows: The earlier version of the map-reduce framework in Hadoop 1.0 is called MR1. The newer version of MapReduce is known as MR2. MR2 is more isolated and scalable as compared to the earlier MR1 system.
What is Flume and Kafka?
