If a small change is made to test_tiered07.py to move a call to checkpoint, the test drops core:
Some things about this:
- If the second checkpoint is just added, instead of removing the one before flush_tier the test still works.
- The test is failing much later. The abort call happens in the part of the test where we try to create a new table of the same name.
- The abort is happening in the tiered server thread getting an error in the copy storage operation.
