cluster/tier : Files skipped during tier query parsing
The tier query parsing code was using fscanf to read each record.
As space is a delimiter for fscanf, filenames containing spaces
caused the parsing to return unexpected values causing various
issues in the tier process, including crashes due to buffer
overflows.
