Hi, I am new to hadoop and looking for some answers to clear my basic concepts on Hadoop.
Will it matter what the data block size is ?
It is recommended to have a block size of 64 MB, but if we want to have the
data block size to 128 MB, should this effect the performance ?
Does the size of the map jobs created on each datanodes in anyway depend the
block size ?
Thanks for the support.
Regards
Syed
