> 1, In fact,SybolicTextInputFormat supports the path with regex .I add some test sql .

> 2, But ,when using CombineHiveInputFormat to combine  input files , It cannot resolve
the path with regex ,so it will get a wrong result.I  give a example ,and fix the problem.
> Table desc :
> {noformat}
> CREATE External TABLE `symlink_text_input_format`(
>   `key` string,
>   `value` string)
> ROW FORMAT SERDE
>   'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
> STORED AS INPUTFORMAT
>   'org.apache.hadoop.hive.ql.io.SymlinkTextInputFormat'
> OUTPUTFORMAT
>   'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
> LOCATION
>   'viewfs://nsX/user/hive/warehouse/symlink_text_input_format'  
> {noformat}
> There is a link file in the dir '/user/hive/warehouse/symlink_text_input_format' ,  
the content of the link file is 
> {noformat}
>  viewfs://nsx/tmp/symlink* 
> {noformat}
> it contains one path ,and the path contains a regex!
> Execute the sql : 
> {noformat}
> set hive.rework.mapredwork = true ;
> set hive.input.format=org.apache.hadoop.hive.ql.io.CombineHiveInputFormat;
> set mapred.min.split.size.per.rack= 0 ;
> set mapred.min.split.size.per.node= 0 ;
> set mapred.max.split.size= 0 ;
> select count(*) from  symlink_text_input_format ;
> {noformat}
> It will get a wrong result :0
