For Hive3, org.apache.hadoop.hive.metastore.api is moved to org.apache.hive:hive-standalone-metastore. We should shade this package as well to avoid ClassNotFoundException

Where is the problem? In Flink? Or in Hive?

Where is the problem? In Flink? Or in Hive?

For all use case where HiveCatalog engaged

  1. HiveCatalog depends on org.apache.hadoop.hive.metastore.api
    image

  2. During the shading phase, all the package pattern org.apache.hadoop.hive is shaded as org.apache.flink.table.store.shaded.org.apache.hadoop.hive
    image

Well for org.apache.hadoop.hive.metastore.api, they exists in org.apache.hive:hive-metastore for Hive2, but is moved to org.apache.hive:hive-standalone-mteastore for Hive3.

This will cause NoClassDefFoundError for org.apache.flink.table.store.shaded.org.apache.hadoop.hive.metastore.api.XXX

Attach the stacktrace

The reason why E2E does not reveal this issue is that the hive docker image is based on Hive2

Currently, we are using Hive2.3 Catalog (metastore client) for Hive 3.1, you can see it in hive.md:

Jar
Hive 2.3+ [flink-table-store-hive-catalog-{{< version >}}_2.3.jar]
Hive 2.2 [flink-table-store-hive-catalog-{{< version >}}_2.2.jar]
Hive 2.1 [flink-table-store-hive-catalog-{{< version >}}_2.1.jar]

If you want to support hive3 by Hive3 catalog, you should modify documentation too.
