A block, sometimes named as a physical record, is a series of bytes or bits, typically containing some whole number of records, having an utmost length, a block size. In HDFS, the default block size is 64 MB. The procedure of putting data into blocks is called blocking while deblocking is the procedure of extracting data from blocks. Blocked data is usually stored in a data buffer and read or written a whole block at a time. I found a resource intellipaat that helped me to understand well the concepts of HDFS.
