> org.apache.hadoop.hive.ql.io.orc.RecordReaderImpl throws NullPointerException when the constructor of its super class org.apache.orc.impl.RecordReaderImpl calls this.close().
> close() mutates the field 'batch', which is initialized after super class constructor is done. Therefore, we need a null check of field 'batch' in close().
