Specifies the maximum amount of bandwidth that each datanode
can utilize for the balancing purpose in term of
the number of bytes per second.
the number of bytes per second. You can use the following
suffix (case insensitive):
k(kilo), m(mega), g(giga), t(tera), p(peta), e(exa)to specify the size
(such as 128k, 512m, 1g, etc.).
Or provide complete size in bytes (such as 134217728 for 128 MB).
