Creating empty index w/ template, delete, recreate gave the following error :
"reason":"Mapping definition for [suggester_name] has unsupported parameters: [payloads : true]"}]
On master node : if running
_cat/shards which should result in an empty result it returns in the logs :
I saw that that issue has been encountered in 2.4 but it seems to be back,
Restarting Elasticsearch on all nodes didn't change anything. I will try to purge all DATA_DIR and give it a try.
