------------------------------------
Summary: [DiskBalancer] Incorrect tracking of DiskBalancer
inProgressTask and balancedByteMap initialisation
Key: HDDS-13278
URL: https://issues.apache.org/jira/browse/HDDS-13278
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Gargi Jaiswal
Assignee: Gargi Jaiswal
This ticket addresses two related issues within the DiskBalancer logic:
# *Incorrect Task Tracking:* The {{DiskBalancerService}} fails to track
in-progress tasks, causing it to constantly over-schedule new balancing
operations. This leads to an excessive task queue and flawed decision-making
based on an inaccurate view of pending work.
# *Uninitialized State Map:* In the {{{}DiskBalancerManager{}}}, the
{{balancedBytesMap}} is never initialized. Consequently, it remains
{{{}null{}}}, and any attempts to record the number of balanced bytes from
datanode reports are silently ignored, preventing proper state tracking.
