--------------------------------
Summary: Duplicated output file path problem
Key: TAJO-1384
URL: https://issues.apache.org/jira/browse/TAJO-1384
Project: Tajo
Issue Type: Bug
Components: storage
Reporter: Jihoon Son
Assignee: Jihoon Son
*Introduction*
When consecutively inserting data into an existing directory, each files must
have different names. To avoid the duplicated name problem, a unique sequence
number is appended to the end of the file name. In addition, the max sequence
number of pre-existing files is first found before starting writing to the
final output directory.
*Problem*
When finding the max sequence number of pre-existing files, those files are not
sorted by their sequence numbers. This finally causes the duplicated file name
problem.
