>    Affects Versions: 1.9.0

> I have a table with 300 columns.
> When I select a query , some null columns are also returned.
> This is the query that I used.
> "select a,b from dfs.root.`/2016/1/17` where a=1"
> For example in this query some columns are returned that "a" value is null.
> I think null values are problems. Because when I add a condition to it like 
> "select a,b from dfs.root.`/2016/1/17` where a=1 and a IS NOT NULL"
> there is not any change and still NULL values are returned.
