             Summary: Make sure qtests clean up copied files from test 
                 Key: HIVE-22899
                 URL: https://issues.apache.org/jira/browse/HIVE-22899
             Project: Hive
          Issue Type: Improvement
            Reporter: Zoltan Chovan
            Assignee: Zoltan Chovan

Several qtest files are copying schema or test files to the test directories 
(such as ${system:test.tmp.dir} and ${hiveconf:hive.metastore.warehouse.dir}), 
many times without changing the name of the copied file. When the same files is 
copied by another qtest to the same directory the copy and hence the test 
fails. This can lead to flaky tests when any two of these qtests gets scheduled 
to the same batch.


In order to avoid these failures, we should make sure the files copied to the 
test dirs have unique names and we should make sure these files are cleaned up 
by the same qtest files that copies the file.
