----------------------------------------
Summary: Tasks need to be sanitized before attempting a diff
operation
Key: AURORA-506
URL: https://issues.apache.org/jira/browse/AURORA-506
Project: Aurora
Issue Type: Story
Components: Client
Reporter: Maxim Khutornenko
Irrelevant thrift TaskConfig fields should not produce a diff noise resulting
in unnecessary instance updates. Couple of observed cases:
- TaskConfig field renaming triggers an instance update when scheduler and
client are on different thrift schemas during the version upgrade period;
- Identity.user field diff prevents a suspended job update to be resumed by a
different user as the update restarts from scratch.
To better protect against the problems above, the client api needs to have
something like DiffSanitizer where both local and remote tasks would be brought
to a common denominator before attempting a diff.
