Hadoop Ecosystems

Well though there are many Ecosystem of Hadoop but their ues is very purposeful to your project. Like for my Project of building and analyzing a datawarehouse for banking I need the below ecosystem.

Hive :- SQL like data base that work on Hadoop MR framework for analyzing the raw data first.
PIG :- An ecosystem that enables various raw data transformation format to an understandable and aggregated format that HDFS can understand and store.
Impala :- An Inmemory columnar database that works with HDFS and is more faster than Hive.
HBASE :- NoSQL database to handle mainly unstructured data.
Oozie :- To schedule a workflow in Hadoop
Hue :- A web based interface of hadoop to manipulate cli options for the ecosystems.

Apart from that in the ecosystem I have used R for analytic purpose and Splunk for graphical reporting. But I have been now working with Tableau.
