URL: https://github.com/apache/doris/pull/47604
### What problem does this PR solve?
This pull request introduces improvements to the removeOldExportJobs()
method in the ExportMgr class, ensuring that it efficiently manages the number
of historical export jobs based on the configured limit. The following changes
have been made:
Logic Enhancement:
- The method now retains a maximum number of historical jobs, removing the
oldest jobs only when the count exceeds the defined limit.
Unit Tests:
- Added a comprehensive unit test for removeOldExportJobs() in the
ExportMgrTest class.
- The test verifies that the method correctly removes jobs based on their
creation time and maintains the maximum allowed number of historical jobs.
- Additional checks ensure that the jobs remaining after the removal process
are the most recent ones.
These changes improve the efficiency and reliability of the job management
system, ensuring that it adheres to the specified constraints while providing
robust testing coverage.
