Thanx @kgyrtkirk for the review. I tried the scenario in HIVE-24224. I think it worked as expected:
```
+-------------------+--------------------+----------------+
| bz2tst2.sequence | bz2tst2.id | bz2tst2.other |
+-------------------+--------------------+----------------+
| 9 | 20200315 X00 1356 | 123 |
| 17 | 20200315 X00 1357 | 123 |
+-------------------+--------------------+----------------+
```
The file in was :
```
printf "offset,id,other\n9,\"20200315 X00 1356\",123\n17,\"20200315 X00 1357\",123\nrst,rst,rst" > data.csv
bzip2 -f data.csv
hdfs dfs -put data.csv.bz2 hdfs://hostname:8020/warehouse/tablespace/external/hive/bz2tst2
```
Table is
```
+----------------------------------------------------+

```
Seems working, the UT was working. :-)
