Gabriel39 opened a new pull request, #52850:
URL: https://github.com/apache/doris/pull/52850
…epare execution (#51492)
Issue Number: close #51491
Problem Summary:
When the queue of the FragmentMgrAsync thread pool is full, newly submitted
tasks are rejected and return early. However, previously submitted tasks may
still be scheduled for execution later. This can lead to premature destruction
of objects such as PipelineFragmentContext and TPipelineFragmentParams that are
referenced by those tasks, resulting in null pointer exceptions during task
execution and ultimately causing a coredump.
The pr policy is to wait until all previously submitted tasks are completed
before returning.
