Amazon EMR 7.1.0 - Hive changes

  • Amazon EMR 7.1 upgrades Hive to Netty 4.1.100.Final to solve the security vulnerabilities in Netty3. Since hive-druid-handler has a dependency on netty3, Hive doesn't have the hive-druid-handler JAR in Hive's classpath in Amazon EMR 7.1. An upcoming Amazon EMR release will include it in Hive's classpath once the Druid handler supports 4.1.100.Final or later versions of Netty. Reach out to Amazon support if you need the hive-druid-handler JAR in Amazon EMR releases 7.1 or higher.
