Yuming Wang updated SPARK-21646:
--------------------------------
    Description: 
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}

{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.

  was:
Hive:
{code:sql}
$ hive -S
hive> create table tmp.wym_spark_123(c1 string, c2 string);
hive> insert into tmp.wym_spark_123 values('92233720368547758071', 'a');
hive> insert into tmp.wym_spark_123 values('21474836471', 'b');
hive> insert into tmp.wym_spark_123 values('10', 'c');
hive> select * from tmp.wym_spark_123 where c1 > 0;
92233720368547758071    a
10      c
21474836471     b
