If a particular file is 50 mb, will the HDFS block still consume 64 mb as the default size? | Hadoop Questions

No, not at all! 64 mb is just a unit where the data will be stored. In this particular situation, only 50 mb will be consumed by an HDFS block and 14 mb will be free to store something else. It is the MasterNode that does data allocation in an efficient manner.
