2.3 Top Reasons Why Companies Implement Hadoop

Hadoop Basics
    1. Economical (Cost Effective):
      • No license
      • It's an open source framework ,
      • If you buy it from Cloudera, Hortonworks., Mapaa, which are different distributions of Hadoop then also its totally free.
    2. Flexible:
      • Hadoop is schema-less, and can absorb any type of data, structured or not, from any number of sources.
      • Data from multiple sources can be joined enabling deeper analyses than any one system can provide.
    3. Scalable:
      • New nodes can be added without needing to change data formats, how data is loaded, how jobs are written, or the applications on top.
      • You can add as many number of nodes as you want depending upon the data size and business requirement.
      • Can process really large data (petabytes)
    4. Solves Big data 3Vs problem:
      • Refer to the chapter one for Big data 3Vs problem
    5. Reliable and Fault Tolerant:
      • When you lose a node, the system redirects work to another location of the data and continues processing without missing a beat.
      • Handles replication
    6. Smart
      • Optimized Compression
      • Query Expression
      • Columnar Caching
