HIVE-27114 adds a new property in hive-site.xml for HMS clients to filter out unwanted partition parameters: hive.metastore.partitions.parameters.exclude.pattern It defaults to "impala_intermediate_stats_chunk%". This excludes the incremental stats of Impala. Impala should set this to an empty string to get rid of the impact. Tests: - Ran CatalogTest#testPullIncrementalStats which failed when running on higher Hive versions that have HIVE-27114.
