Review Comment:
   I think just `void prepareTable(String tableName, boolean schemaV3, int 
recordsCount)` is OK, we can pass `5` for other method (like 
`prepareTable(KEY_TABLE, true, 5)`).

Review Comment:
   We can automatically create parent directory for both recordsPerFile > 0 and 
recordsPerFile == 0, current, not give the `--max-records-per-file` the parent 
directory  will not be created automatically.
   Maybe just need remove the `if`.
