Description

We currently have a single core integration test, RecoveryWithUnsupportedIndicesIT, which checks ancient indexes are not loadable, with an expected error message. However, the test was written for the upgrade to 2.0, and so deals with a 0.20 index. We should instead have a qa test which builds an index using the last version before our full cluster restart supported versions, and checks the node failure.

Research direction
Examine the existing test RecoveryWithUnsupportedIndicesIT in the core test suite to understand the current approach. Then, implement a QA test that builds an index using the last version before the supported versions for full cluster restart, and verify that the node failure is correctly handled. The test should be added in the QA module following the project's testing conventions.
