> 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().
