---------------------------------
Summary: Improvmemt allocation policies empty disk scheduler
Key: TAJO-181
URL: https://issues.apache.org/jira/browse/TAJO-181
Project: Tajo
Issue Type: Improvement
Components: storage
Affects Versions: 0.2-incubating
Reporter: hyoungjunkim
Priority: Minor
Current new StorageManager assigns to DiskScanScheduler with disk id regardless
of each DiskScanScheduler's queue size. This policy is the cause of poor
performance.
If some DiskScanScheduler is empty, the DiskScanScheduler is assigned a
priority.
