Only close scheduler in SpecCluster if it exists#6888
Merged
Conversation
In failure cases the scheduler may not have been created but close is
still called, providing a traceback like the following:
```python-traceback
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/mrocklin/workspace/distributed/distributed/deploy/spec.py", line 275, in __init__
self.sync(self._start)
File "/home/mrocklin/workspace/distributed/distributed/utils.py", line 338, in sync
return sync(
File "/home/mrocklin/workspace/distributed/distributed/utils.py", line 405, in sync
raise exc.with_traceback(tb)
File "/home/mrocklin/workspace/distributed/distributed/utils.py", line 378, in f
result = yield future
File "/home/mrocklin/mambaforge/lib/python3.9/site-packages/tornado/gen.py", line 762, in run
value = future.result()
File "/home/mrocklin/workspace/distributed/distributed/deploy/spec.py", line 318, in _start
await self._close()
File "/home/mrocklin/workspace/distributed/distributed/deploy/spec.py", line 434, in _close
await self.scheduler.close()
AttributeError: 'NoneType' object has no attribute 'close'
```
This wasn't really an issue (things were already broken) but makes
tracking down the real issue more of a pain.
