kasakrisz opened a new pull request #2022: URL: https://github.com/apache/hive/pull/2022
### What changes were proposed in this pull request? Set `materializationTime` when updating `CreationMetadata` using `ObjectStore.updateCreationMetadata` ### Why are the changes needed? When Rebuilding a MaterializedView a new `CreationMetadata` instance is created for the view which contains updated information like `ValidTxnList`. Initially this object has a `materializationTime` value with `0` and this is going to be stored in the `HiveMaterializedViewsRegistry` wrapped by the `RelOptMaterialization` object represents the view. However the `materializationTime` value stored in the MetaStore is recalculated and stored during the update hence MS and the registry has different values. This can lead unnecessary registry refresh or even `NullPointerException` as the jira explains. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? ``` mvn test -Dtest=TestObjectStore#testUpdateCreationMetadataSetsMaterializationTime -pl standalone-metastore/metastore-server ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
