title: Hive : Query Table with column name having a keyword and a space
body: <p>I have a table test. It has a column 'abc group'
  I want to have a query
  select <code>abc group</code>,sum(someothercolumn)
  from test group by <code>abc group</code></p>
  
  <p>Even with using backticks (`), query fails. hive starts to consider group in the column name as group keyword</p>
