-------------------------------------
Summary: Buddy Allocator memory accounting does not account for
failed allocation attempts
Key: HIVE-21689
URL: https://issues.apache.org/jira/browse/HIVE-21689
Project: Hive
Issue Type: Bug
Components: llap
Reporter: slim bouguerra
Assignee: slim bouguerra
Allocation method on Buddy Allocator, does not release the reserved memory in
case we failed to allocate the full sequence.
Simple example:
Assume We have an allocation request of 1kb.
Will call reserver and reserve 1KB.
Try to allocate will fail due to race condition.
Try to discard will fail due to no space.
At this point will exit without releasing the reserved memory.
