This upgrade will generate huge log spam in elastic config:
One is related to a bug in elastic we had to workaround and now fixed (but generates deprecation warning):
[2017-05-10T02:41:46,682][WARN ][org.elasticsearch.deprecation.common.ParseField] Deprecated field [max_determined_states] used, expected [max_determinized_states] instead
And will be fixed by deploying https://gerrit.wikimedia.org/r/#/c/353100/
Another lines that is currently spamming deployment-prep logs is :
[2017-05-10T02:41:41,311][WARN ][org.elasticsearch.deprecation.rest.RestController] Content type detection for rest requests is deprecated. Specify the content type using the [Content-Type] header.
This one is unexpected and we should probably look into fixing before upgrading the production cluster.
