| Question ID 12478 | Which best describes how TextInputFormat processes input files and line breaks? |
| Option A | Input file splits may cross line breaks. A line that crosses file splits is read by the RecordReader of the split that contains the beginning of the broken line. |
| Option B | Input file splits may cross line breaks. A line that crosses file splits is read by the RecordReaders of both splits containing the broken line. |
| Option C | The input file is split exactly at the line breaks, so each RecordReader will read a series of complete lines. |
| Option D | Input file splits may cross line breaks. A line that crosses file splits is ignored. |
| Option E | Input file splits may cross line breaks. A line that crosses file splits is read by the RecordReader of the split that contains the end of the broken line. |
