             Summary: ORC RecordReaderImpl throws NPE when close() is called 
from the constructor
                 Key: HIVE-27344
                 URL: https://issues.apache.org/jira/browse/HIVE-27344
             Project: Hive
          Issue Type: Bug
    Affects Versions: 4.0.0-alpha-2, 3.1.3
            Reporter: Seonggon Namgung
            Assignee: Seonggon Namgung


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().
