Preserve the public HDFSUtils name during migration.
External Scala code that imports HDFSUtils will no longer compile after this rename. Keep a deprecated forwarding object or provide another compatibility path while introducing HadoopFsUtils.

Define the input path before validating the read options.
inpudDataPath is not declared in the README example. Renaming only the call to inputDataPath would leave the example with another undefined identifier.

Check every fixed-length file before validation succeeds.
If a directory contains at least 50 files, the scanner examines only its first 50 for record-size mismatches. validateLoad can therefore succeed when a later file has an invalid size. Make the size check inspect every resolved file, stopping at the first mismatch if needed. (raw.githubusercontent.com)
