CREATE External TABLE `symlink_text_input_format`(
`key` string,
`value` string)
ROW FORMAT SERDE

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.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 result a wrong result :0
At the same time ,I add a test case in the patch.
