(I upgrade to 1.2.0) BUT I am using, AWS elastic search service.

aws-sdk-v1 (1.64.0)

elasticsearch (1.0.14)  
elasticsearch-api (1.0.14)  
elasticsearch-transport (1.0.14)

fluent-logger (0.4.10)  
fluent-mixin-config-placeholders (0.3.0)  
fluent-mixin-plaintextformatter (0.2.6)  
fluent-mixin-rewrite-tag-name (0.1.0)  
_fluent-plugin-elasticsearch (1.2.0)_  
fluent-plugin-geoip (0.5.1)  
fluent-plugin-mongo (0.7.10)  
fluent-plugin-rewrite-tag-filter (1.4.1)  
fluent-plugin-s3 (0.5.9)  
fluent-plugin-scribe (0.10.14)  
fluent-plugin-script (0.0.2)  
fluent-plugin-td (0.10.27)  
fluent-plugin-td-monitoring (0.2.1)  
fluent-plugin-webhdfs (0.4.1)

\*I think that is a AWS issue, \* that returns a different JSON for the same  
API, (no address data) as you said before. It's a pity... because if they  
change the standard behavior, a lot of plugins are not going to work.
