title: How to handle YYYYMM data in Impala?
body: <p>I have data sources that provide date information in the format YYYYMM, for example, 201805. What is the best Impala datatype to deal with such data? </p>
  
  <p>I could use string but that would restrict the ability to do date math on that data field.</p>
  
  <p>Please suggest.</p>
