Upgrade to a newer Elasticsearch version ?

[gabrielcrowdtilt]

The requirements state the Elasticsearch connector depends on Elasticsearch 1.2.1

But that version is about a year old, and they're now all the way up to 1.6.x

Not sure if it's an easy change or fairly involved to upgrade.

You should be able to just specify the new version in your pom.xml. The awslabs/cloudwatch-logs-subscription-consumer project is successfully using the amazon-kinesis-connectors library with v1.6 of the Elasticsearch client:

There might be a bit more work involved (not a Java expert - not at all): Elasticsearch used to shade its dependencies and to relocate packages. We no longer use shading or relocation. You might need to change your imports to the original package names, from: https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking_20_java_api_changes.html#_shading_and_package_relocation_removed
