priyeshkaratha opened a new pull request, #9933:
URL: https://github.com/apache/ozone/pull/9933
## What changes were proposed in this pull request?
This pull request resolves a data consistency issue within Recon's task
management by ensuring that after a reprocess operation, the system correctly
updates its internal references to ReconOmTask instances. This prevents tasks
from operating on stale in-memory states, which could lead to incorrect data
aggregation. The changes also enhance the robustness of the re-initialization
process with improved error handling and are thoroughly validated by a new
dedicated test case.
The reInitializeTasks method in ReconTaskControllerImpl was updated to
correctly replace existing ReconOmTask instances with newly created staged
tasks after a reprocess operation. This ensures that subsequent delta events
are processed by the fresh in-memory state of the tasks, preventing stale data
issues.
A new JUnit test, TestOmTableInsightTaskStaleCounterAfterReinit, was added.
This test provides end-to-end validation that reInitializeTasks correctly
updates task references and maintains accurate counters after
re-initialization, specifically demonstrating the fix for stale counter issues.
