[GitHub] [ambari] aonishuk opened a new pull request #3273: AMBARI-25604. During blueprint deploy tasks sometimes fail due to KeyError
aonishuk opened a new pull request #3273:
URL: https://github.com/apache/ambari/pull/3273
## What changes were proposed in this pull request?
During blueprint deploy we don't rely on topology cache since https://issues.apache.org/jira/browse/AMBARI-23660
So topology is send with command. BUT the problem occurs when we still try to generate it on agent and fail.
We need to ignore not fail on KeyError there
```ERROR 2020-12-10 06:30:09,350 CustomServiceOrchestrator.py:459 - Caught an exception while executing custom service command: <type 'exceptions.KeyError'>: 10; 10

KeyError: 10```
