multi-digit ycsb versions (0.10.0+) causing 'Unexpected second line' error

[flint-dominic]

Any version i use above 0.9.0 causes 'Unexpected second line', I can comment out the error to have it run successfully, but this may lead to other complications. the error doesn't even print out the 'command_line' variable correctly:

Would you provide the command?

Note that pairing --ycsb_version=0.11.0 with --ycsb_measurement_type=hdrhistogram does work. Neither setting works if used individually.
