Let’s say I have a file of 130 MB and I put it on HDFS. The first block will have 128 MB and 2nd block will have 2 MB. Now if there is another file of 132 MB also put in HDFS then again, this one will have first block of 128 MB and 2nd block of 4 MB. Can the 2nd blocks of each of these files be shared in single block? Means a block containing 2 MB of one file and 4 MB of another file. Is it possible?
