title: Hive table reading from GZIP contains meta information like file name in the first row
body: <p>I have created an external table in hive pointing to a gzip file</p>
  
  <pre><code>create external table IF NOT EXISTS raw_CN (
  column1                        string,
  column2                       string,
  column3            string,
  column4       string,
  column5            string,
  column6          string,
  column7            string,
  column8           string,
  column9                        string,
  column10        string
  </code></pre>
  
  <p>)
     PARTITIONED BY (day_id string, file_type string)
     row format  delimited fields terminated by  '|'
     STORED AS TEXTFILE;</p>
  
  <p>Added the  partition:</p>
  
  <pre><code>Alter table raw_CN add partition (day_id = '20140815' , file_type = 'Daily' ) location    '/mapr/mapr.cluster/CN/20140501/Daily';
  </code></pre>
  
  <p>Placed the gzip file at the above location</p>
  
  <p>However when I query the table, the first row also gives me some file level information (there is no header in the file).  How do I resolve this issue from the first row (rest of the rows are fine):</p>
