Description

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().
