Hi everybody, 
I have a big problem with the blocksize configuration I tried different configurations at
the hdfs-site config (datanodes and namenodes have the same configuration)

i tried 

But in all cases when I run a map-reduce job i found that the amount of slots is proportional
to 64M blocks and if a run a du -hs in all datanode a found that the block files are 65M

For example 

65M	blk_720821373677199742
