Hi, java.lang.NoSuchMethodError: org.apache.flink.util.InstantiationUtil.isSerializable(Ljava/lang/Object;)Z at org.apache.flink.streaming.connectors.elasticsearch.ElasticsearchSinkBase.<init>(ElasticsearchSinkBase.java:195) at org.apache.flink.streaming.connectors.elasticsearch5.ElasticsearchSink.<init>(ElasticsearchSink.java:95) at org.apache.flink.streaming.connectors.elasticsearch5.ElasticsearchSink.<init>( The reason for this exception is because the `isSerializable `method only exists in 1.3-SNAPSHOT of `flink-core` at the moment. These kind of errors can usually be expected to happen if you are using mismatching versions of Flink libraries and core Flink dependencies.
Elasticsearch 5 will be released with Flink 1.3.0 (targeted release time is end of May). For the time being, if Elasticsearch 5 is a must, you could try implementing a copy of the `isSerializable` method under the exact same package path / method and class name in your own project. However, I can not guarantee that this will work as there may be other conflicts. - Gordon On March 2, 2017 at 10:47:52 PM, Fábio Dias (fabiodio...@gmail.com) wrote: java.lang.NoSuchMethodError: org.apache.flink.util.InstantiationUtil.isSerializable(Ljava/lang/Object;)Z at org.apache.flink.streaming.connectors.elasticsearch.ElasticsearchSinkBase.<init>(ElasticsearchSinkBase.java:195) at org.apache.flink.streaming.connectors.elasticsearch5.ElasticsearchSink.<init>(ElasticsearchSink.java:95) at org.apache.flink.streaming.connectors.elasticsearch5.ElasticsearchSink.<init>(
