-------------------------------

             Summary: Intermittent failures of ElasticSearch indexing on startup
                 Key: ZEST-56
                 URL: https://issues.apache.org/jira/browse/ZEST-56
             Project: Zest
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Paul Merlin
            Assignee: Paul Merlin
             Fix For: 2.1


ElasticSearch can take some time to get ready for queries and actual activation code do not
wait for it's readiness.

If a query is sent to ES right after activation there's a chance it's not ready and one gets
the following error: "Failed to execute phase [query], all shards failed".

This error pops up quite often when using embedded ES in unit tests.

To mitigate this we should, on activation:
- ensure the Qi4j index is refreshed
- wait for ES yellow status (the primary shard is allocated but replicas may not be)
