-------------------------------------

             Summary: flink-connector-hive builds might be blocked (but not fail) because Maven tries to access conjars.org repository (which times out)
                 Key: FLINK-33040
                 URL: https://issues.apache.org/jira/browse/FLINK-33040
             Project: Flink
          Issue Type: Bug
          Components: Build System / CI
    Affects Versions: 1.17.1, 1.16.2, 1.18.0, 1.19.0
            Reporter: Matthias Pohl


We experienced timeouts when building {{flink-connectors/flink-connector-hive}} because Maven tries to access {{http://conjars.org}} to retrieve meta information for  {{net.minidev:json-smart}} which fails because the repository is gone.

[~gunnar.morling] already described this in his blog post https://www.morling.dev/blog/maven-what-are-you-waiting-for/. 

We investigated where this {{conjar}} repository is coming from. It turns out that the [org.apache.hive:hive-exec:2.3.9|https://repo1.maven.org/maven2/org/apache/hive/hive-exec/2.3.9/hive-exec-2.3.9.pom] dependency derives from its parent [org.apache.hive:hive:2.3.9|https://repo1.maven.org/maven2/org/apache/hive/hive/2.3.9/hive-2.3.9.pom] which pulls in the conjar.org repository:
{code}
<repository>
  <id>conjars</id>
  <name>Conjars</name>
  <url>http://conjars.org/repo</url>
  <layout>default</layout>
  <releases>
    <enabled>true</enabled>
    <updatePolicy>always</updatePolicy>
    <checksumPolicy>warn</checksumPolicy>
  </releases>
</repository>
{code}

The subsequent hive dependency [org.apache.hive:hive:3.0.0|https://repo1.maven.org/maven2/org/apache/hive/hive/3.0.0/hive-3.0.0.pom] doesn't have this reference anymore.
