             Summary: trailing spaces in partition column will be treated 
differently
                 Key: HIVE-13618
                 URL: https://issues.apache.org/jira/browse/HIVE-13618
             Project: Hive
          Issue Type: Bug
            Reporter: Pengcheng Xiong
            Assignee: Pengcheng Xiong


We store the partition spec value in the metastore. In mysql (and derby i 
think), the trailing space is ignored. That is, if you have a partition column 
"col" (type varchar or string) with value "a " and then select from the table 
where col = "a", it will return. However, in postgres and Oracle, the trailing 
space is not ignored.
