Services that timeout should be handled differently on subsequent requests
--------------------------------------------------------------------------
Key: UIMA-1127
URL: https://issues.apache.org/jira/browse/UIMA-1127
Project: UIMA
Issue Type: Improvement
Components: Async Scaleout
Affects Versions: 2.2.2
Reporter: Eddie Epstein
Assignee: Jerry Cwiklik
When a request times out, the service should be put into a "questionable"
state. Requests to a service in questionable state will then use a different
logic: first send a getMeta request with a short timeout; if the getMeta
succeeds, the questionable state is removed and the normal request is sent; if
getMeta fails, an error is returned for the request with the state unchanged.
This logic should be used for both API and aggregate clients.
