> Hudi currently does not work with AWS Glue Catalog. The issue/exception it
> runs into has been reported here as well
> [issue|https://github.com/apache/incubator-hudi/issues/954] .
> As mentioned in the issue, the reason for this is:
> * Currently Hudi is interacting with Hive through two different ways:
> ** Creation of table statement is submitted directly to Hive via JDBC
> [https://github.com/apache/incubator-hudi/blob/master/hudi-hive/src/main/java/org/apache/hudi/hive/HoodieHiveClient.java#L472]
> . Thus, Hive will internally create the right metastore client (i.e. Glue if
> {{*hive.metastore.client.factory.class*}} is set to
> {{*com.amazonaws.glue.catalog.metastore.AWSGlueDataCatalogHiveClientFactory*}}
> in hive-site)
> ** Whereas partition listing among other things are being done by directly
> calling hive metastore APIs using hive metastore client:
> [https://github.com/apache/incubator-hudi/blob/master/hudi-hive/src/main/java/org/apache/hudi/hive/HoodieHiveClient.java#L240]
> * Now in Hudi code, standard specific implementation of the metastore client
> (not glue metastore client) is being instantiated:
> [https://github.com/apache/incubator-hudi/blob/master/hudi-hive/src/main/java/org/apache/hudi/hive/HoodieHiveClient.java#L109]
> .
> * Ideally this instantiation of metastore client should be left to Hive
> through
> [https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L5045]
> for it to consider other implementations of metastore client that might be
> configured through {{*hive.metastore.client.factory.class*}} .
> That is the reason that table gets created in Glue metastore, but while
> reading or scanning partitions it is talking to the local hive metastore
> where it does not find the table created.
