What's wrong with the code in PruningSuite?
````scala
createPruningTest("Column pruning - explode with aggregate",
"SELECT name, sum(d) AS sumd FROM person LATERAL VIEW explode(data) d
AS d GROUP BY name",
Seq("name", "sumd"),
Seq("name","data"),
Seq.empty)
createPruningTest("Column pruning - outer explode with limit",
"SELECT name FROM person LATERAL VIEW OUTER explode(data) outd AS d" +
" where name < \"C\" limit 3",
Seq("name"),
Seq("name", "data"),
Seq.empty)
createPruningTest(s"Column pruning - select all without explode optimze -
query test",
"SELECT * FROM person LATERAL VIEW OUTER explode(data) outd AS d WHERE
20 < age",
Seq("name", "age", "data", "d"),
Seq("name", "age", "data"),
Seq.empty)
`````
