Review comment:
The compiler prints warnings for the code:
```
/Users/maxim/proj/orc-eliminate-warning/sql/hive/src/main/java/org/apache/hadoop/hive/ql/io/orc/SparkOrcNewRecordReader.java
Warning:(44, 13) java: getTypes() in org.apache.orc.Reader has been
deprecated
Warning:(47, 24) java: getTypes() in org.apache.orc.Reader has been
deprecated
```
