             Summary: Added resource path is sent to cluster as an empty string when externally removed
                 Key: HIVE-12365
                 URL: https://issues.apache.org/jira/browse/HIVE-12365
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 1.2.1
            Reporter: Chaoyu Tang
            Assignee: Chaoyu Tang


Sometimes the resources (e.g. jar) added via command like "add jars <filepath>" are removed externally from their filepath for some reasons. Their paths are sent to cluster as empty strings which causes the failures to the query that even do not need these jars in execution. The error look like as following:
{code}
