> How to reproduce:
> hive:
> {code:sql}
> $ hive -S
> hive> create table spark_21646(c1 string, c2 string);
> hive> insert into spark_21646 values('92233720368547758071', 'a');
> hive> insert into spark_21646 values('21474836471', 'b');
> hive> insert into spark_21646 values('10', 'c');
> hive> select * from spark_21646 where c1 > 0;
> 92233720368547758071  a
> 10    c
> 21474836471   b
> hive>
> {code}
> spark-sql:
> {code:sql}
> $ spark-sql -S
> spark-sql> select * from spark_21646 where c1 > 0;
> 10      c                                                                     
>   
> spark-sql> select * from spark_21646 where c1 > 0L;
> 21474836471   b
> 10    c
> spark-sql> explain select * from spark_21646 where c1 > 0;
> == Physical Plan ==
> *Project [c1#14, c2#15]
> +- *Filter (isnotnull(c1#14) && (cast(c1#14 as int) > 0))
>    +- *FileScan parquet spark_21646[c1#14,c2#15] Batched: true, Format: 
> Parquet, Location: 
> InMemoryFileIndex[viewfs://cluster4/user/hive/warehouse/spark_21646], 
> PartitionFilters: [], PushedFilters: [IsNotNull(c1)], ReadSchema: 
> struct<c1:string,c2:string>
> spark-sql> 
> {code}
> As you can see, spark auto cast c1 to int type, if this value out of integer 
> range, the result is different from Hive.
