Hi,
I am new to Hadoop and would like to understand how exactly are Hadoop and its
associated technologies (like Cassandra, Hive, Pig,etc..) used to achieve a
business goal ? So lets say an organization has Hadoop and Cassandra or MongoDB
and everything up and running. Then what ? What do you do with it and How ?
What are the typical business applications that run against it ? Do you have to
write something in Java/Python/PHP to get anything you want out of it ?
Like for example if the Oracle Rdbms was the new thing today then the answer to
this question would be - it can be used to develop OLTP or Data Warehouse or
Analytical applications using Java/php and PL/SQL, or using Informatica, Cognos
and such tools to move and analyze data. I guess I am looking for just real
world day-to-day use cases of the Hadoop ecosystem.
Would appreciate if anyone can put this into context and perspective for me.
Thanks!
-Percy.
