BLOCK SIZE IN HADOOP

Image
 HADOOP MINIMUM AND MAXIMUM  BLOCK SIZE IN HADOOP DISTRIBUTED FILE SYSTEM MINIMUM SIZE - 512 bytes is the minimum block size which is accepted in the Hadoop distributed file system. Here I have first given 511 bytes which are not accepted by it and so finally it accepts the minimum size as 512 bytes.  MAXIMUM SIZE -  280375465082880 bytes is the maximum block size accepted by the Hadoop distributed file system. Here when I gave 281474976710656 bytes as block size it throws one exception " UNEXPECTED VALUE FOR THE BLOCK SIZE ". So the maximum block size is 280375465082880 bytes. Thank You for Reading !!
