Subject [jira] [Commented] (FLINK-10107) SQL Client end-to-end test fails for releases
Date Mon, 13 Aug 2018 12:58:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-10107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16578246#comment-16578246

ASF GitHub Bot commented on FLINK-10107:

zentol commented on issue #6534: [FLINK-10107] [sql-client] Relocate Flink Kafka connectors
for SQL JARs
URL: https://github.com/apache/flink/pull/6534#issuecomment-412508686
 
 
   so, given that we do not care about situations where multiple connectors are on the CP
(as concluded in previous comments), this means that this also affects a single kafka-connector
jar in isolation? I.e. this **not** being a class between **jars**?

> It seems that SQL JARs for Kafka 0.10 and Kafka 0.9 have conflicts that only occur for
releases and not SNAPSHOT builds. This might be due to their file name. Depending on the file
name either 0.9 is loaded before 0.10 and vice versa.
