Underlying file system Block size

Hi All,

To my knowledge, HDFS block size is 64MB - fairly large. Is this a
requirement from a file system, if one wishes to implement Hadoop on top of
it ? Or is there a way to get along with a file system supporting a smaller
block size such as 1M or even less ? What is the case for existing, non
HDFS, implementations of Hadoop (such as S3, KFS) ?

Thanks for any input,
Naama
