Limit for Namenode Quantity

Question

Assuming the size of one name node to be 32 GB, How many files can I store in a single name node?

Answer 1

Each file Schema = 150bytes  

Block schema for the file=150bytes

1million files each with 1 block will consume=300*1000000=300000000bytes =300MB provided with a replication factor of 1.

And with a replication factor of 3, it requires 900MB.

For every 1GB you can store 1million files.
