Weijie Guo created FLINK-30359: ---------------------------------- Summary: Encountered NoClassDefFoundError when using flink-sql-connector-elasticsearch6 Key: FLINK-30359 URL: https://issues.apache.org/jira/browse/FLINK-30359 Project: Flink Issue Type: Bug Components: Connectors / ElasticSearch Reporter: Weijie Guo Attachments: image-2022-12-11-01-09-47-337.png
When I use sql-client to submit job that sink data to elasticsearch, it seems that the `NoClassDefFoundError` arises as shown in the figure below. Note that the connector jar I used is flink-sql-connector-elasticsearch6-4.0-SNAPSHOT.jar, it is a uber jar compiled from flink-connector-elasticsearch repo's main branch. !image-2022-12-11-01-09-47-337.png|width=596,height=285! Through some investigations, I found that in flink-sql-connector-elasticsearch6 module's pom.xml, we manually excluded the `com.carrotsearch: hppc` dependency, which is no problem for the 6.3.1 version of elasticsearch. However, FLINK-25189 bump this to 6.8.20, which does requires the dependence of hppc. Therefore, an `NoClassDefFoundError` occurred. -- This message was sent by Atlassian Jira (v8.20.10#820010)
