Difference between Hadoop and Apache Spark

Hadoop and Apache Spark are seen as the competitors in the world of big data, but now the growing consensus is that they are better convention in together. Here is a brief look at what they do and how they are compared.  1. They do different things: Both are the big-data frameworks, but they do not serve the same purposes. Hadoop is a distributed data infrastructure. It also Indexes and keep track of that data, enabling big-data processing and analytics. On the other hand, Spark is a data processing tool. Secondly, both can be used individually, without the other. 3. Spark is faster 4. You may not need Spark's speed: Spark is fit for real-time marketing campaigns, online product recommendations, cybersecurity analytics and machine log monitoring. 5. Failure recovery: differently, but still good. Read more at: http://www.computerworld.com/article/3014516/big-data/5-things-to-know-about-hadoop-v-apache-spark.html

Choosing a Hadoop Distribution

Choosing the right Hadoop distribution can be a tricky process. There are 4 basic categories that businesses should look at for specific qualifying criteria.
1. Performance
Hadoop is widely chosen as a data platform due to its high performance achieved by replacing the stock MapReduce by Apache Spark. However not all operations need such superior hardware and a business must choose its hardware on basis of the operations it hopes to perform.
2. Dependability
When looking for a distribution, dependability is a significant but rare feature. Only few implementations in Hadoop can guarantee a system availability of 99.999%. Look for a distribution that provides Self-Healing, No Downtime Upon Failure, Tolerance of Multiple Failure, 100% Commodity Hardware, No Additional Hardware Requirements, Ease of Use, Data Protection and Disaster Recovery.
3. Manageability
Look for a distribution that has intuitive administrative tools that assist in management, troubleshooting, job placement and monitoring.
4. Data Access
Gathering and storing data is just the beginning of the process. What really matters is that the stored data must me easily accessible for further processing. Look for a distribution that provides
• Full access to the Hadoop file system API
• Full POSIX read/write/update access to files
• Direct developer control over key resources
• Secure, enterprise grade search
• Comprehensive data access tooling
Hopefully these four specification along with your criterions will enable you to choose the best Hadoop distribution for you.

Spark or Hadoop Which is a better Big Data framework?

Hadoop, for many years, was the leading open source Big Data framework but recently the newer and more advanced Spark has taken over. Spark is reported to be 100 times faster although it lacks its own distributed storage system. For this reason many projects involve installing Spark on top of Hadoop, where Spark’s advanced analytics can make use of data stored using the Hadoop Distributed File System (HDFS).
What really gives Spark the edge is speed. Spark handles most of its operations ‘in memory’- copying them from the distributed physical storage into far faster logical RAM memory. Spark’s speed of handling advanced data processing tasks such as real time stream processing and machine learning is much more than what could be achieved by Hadoop. Faster dynamic data handling gives Spark the upper hand over Hadoop.
However it must be concluded that these two frameworks are not necessarily mutually exclusive and do not perform exactly the same tasks. In fact using both of them together can actually provide better results than using either one separately.
