Answer» If we store too MANY small files in a CLUSTER on HDFS what happen? If we store too many small files in a cluster on HDFS then it will GENERATES a lot of metadata files. And the problem is that to store these metadata in the RAM will CREATE a challenge as each file, directory or block need 150 BYTES for metadata. So the size of cumulative of metadata will be too large.
