Different Structures
In Commercial IT we have structured data and query and save
to a database. When we want to tackle bigdata projects,
rather than centralising the data we spread it out. In this
illustration, we have a client with a query. The data is spread
across a number of nodes and the name node manages the
spread of the data and data locations. The master node deals
with the query and submits jobs to each slave node to query
their local dataset. The master node collates the results and
returns the answer to the client.
