    Affects Versions: 1.9.0
            Reporter: mehran


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.
If we?
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
