Replication Factor in Hadoop

Question

I have 10 TB data and the whole size of the combined cluster is 14 TB
I have set the Replication factor to 2.

In this case how it will replicate the data?

Due to the Replication factor, the minimum size of the storage on the cluster must be double the size of the Data,

Is this something that Hadoop can't solve, or its a loophole?

Answer 1

If you have provided a replication factor of 2 and the free space available on the cluster is not twice the amount of data to be replicated, it will result in an under-replicated block.  

It's not something that's unsolvable.

It's as simple as that, you can't fit in something if you don't have space. It can't appear magically. Dude.
