Hi all,
ES 2.0 doesn't allow . in field name anymore. As a result, writing metrics
to ES will give the following errors
:response=>{"create"=>{"_index"=>"samza_metrics-2016.04.21",
"_type"=>"samza_metrics", "_id"=>"AVQ6FgE-3mvK_4wEEW2o", "status"=>400,
"error"=>{"type"=>"mapper_parsing_exception", "reason"=>"Field name
[org.apache.samza.container.TaskInstanceMetrics] cannot contain '.'"}}},
:level=>:warn}
I am thinking of either
1. look into logstash plugins
2. have stream processing job to replace '.' with another character.
I am curious how other people solve this problem.
Thanks,
George
