             Summary: Fix data corruption when using multi-byte line.delim with text format tables
                 Key: HIVE-30155
                 URL: https://issues.apache.org/jira/browse/HIVE-30155
             Project: Hive
          Issue Type: Bug
            Reporter: Butao Zhang


•
Problem: HiveIgnoreKeyTextOutputFormat truncates multi-byte line.delim to its first byte via charAt(0), and TextInputFormat ignores line.delim entirely (splits on \n only), causing record misalignment and data loss for tables with multi-byte line delimiters such as \002\n.
•
Fix: Write full multi-byte delimiter bytes in HiveIgnoreKeyTextOutputFormat.getHiveRecordWriter(); propagate line.delim to textinputformat.record.delimiter in HiveInputFormat.getRecordReader() so Hadoop's LineRecordReader splits on the complete delimiter sequence.
