Sounds reasonable. @kevinearls, given that you are working closer with ES nowadays, could you please review this?

[jpkrohling]

@sniperking1234, is this feature available at Jaeger already?

[kevinearls]

@jpkrohling this depends on jaegertracing/jaeger#2637 and jaegertracing/spark-dependencies#101

@sniperking1234 After those two are merged I'd like to see an E2E test for this. You could either add a case to test/e2e/elasticsearch_test.go or modify one of the two test cases that use indices.
