This reads as if failover/DR is assumed by default. I’ve asked the contributor to add a few usage use cases in the write-up to make the expectations explicit. |

#10226
Purpose of this pull request
This PR improves Hive connector metastore HA by:
Using RetryingMetaStoreClient (when available) for metastore retry/failover, with a safe fallback to HiveMetaStoreClient.
Supporting comma-separated metastore_uri (with whitespace trimming), so users can configure multiple HMS endpoints for automatic failover.
Fixing HiveServer2 JDBC URL derivation when metastore_uri contains multiple URIs (derive from the first URI only).
Does this PR introduce any user-facing change?
Yes.
metastore_uri now supports multiple HMS URIs separated by commas (whitespace is allowed), and the connector will fail over to the next available metastore if the first one is unreachable.
How was this patch tested?
Unit tests added: HiveMetaStoreCatalogMetastoreUrisTest.java
E2E tests added: HiveIT.java and configs:
fake_to_hive_metastore_uri_failover.conf
hive_to_assert_metastore_uri_failover.conf
