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

Hey,

all you need to do is to upgrade those plugins as well. They are provided with every release. No need for rolling back.
