title: How it is possible that display results change even no transfromation are run between?
body: <p>I have weird issue with in Databricks environment. 
  I am trying to do some debugging but the display results are not consistent with the code. The display results change even there is nothing run in between the display (df.filter[df[col]=='value'])</p>
  
  <p>Have anyone encountered this kind of thing before?</p>
