If you use Elasticsearch plugins, be very careful about compatibility.
I found this out to my cost when moving from ES5.01->ES5.02 ... both analysis-icu and analysis-phonetic report "
rg.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: Plugin [analysis-icu] is incompatible with Elasticsearch [5.0.2]. Was designed for version [5.0.1]"
Would'nt have expected this for such a minor revision ... so user beware. Eventually rolled back to 5.01 - Disappointing
rolled forward to ES5.02, uninstalled and reinstalled It's done the trick! - working now.
an elasticsearch-plugin upgrade xxxxxx where xxxxxx would be nice !
