------------------------------------------
Thanks Brahma for updating the patch!
{code}
+ throw new HadoopIllegalArgumentException(
+ "Error: Block Size in bytes must be a multiple of \" +\n"
+ + " \"bytes per checksum:");
{code}
1. Would you remove unnecessarily whitespaces and {{\n}} in the error message?
2. Would you remove trailing whitespace?
> [ NN Bench ] Refactor nnbench as a Tool implementation.
