zabetak opened a new pull request, #6615: URL: https://github.com/apache/hive/pull/6615
### What changes were proposed in this pull request? - Delete the druid-handler module (storage handler, SerDe, I/O formats, Kafka ingestion support, Kerberos security utilities) - Delete the itests/qtest-druid module (MiniDruidCluster, test drivers) - Remove all Druid-related query test files (.q and .q.out) - Remove hive.druid.* configuration variables from HiveConf - Remove Druid constants and calcite-druid dependency - Remove Calcite optimizer rules: HiveDruidRules, DruidSqlOperatorConverter, SortedDynPartitionTimeGranularityOptimizer - Remove DruidQuery handling from CalcitePlanner, HiveVolcanoPlanner, HiveFilterProjectTransposeRule, HiveRelFieldTrimmer, ASTBuilder, ASTConverter, and HiveMaterializedViewsRegistry - Remove DRUID/DRUID_LOCAL/DRUID_KAFKA cluster types from test infra - Relocate Kafka test utilities (SingleNodeKafkaCluster, Wikipedia) from itests/qtest-druid to itests/util under org.apache.hadoop.hive.kafka - Update itests/util dependencies to use kafka artifacts directly instead of pulling them transitively via hive-it-druid ### Why are the changes needed? The Druid integration is broken for the past 5 years and seemingly unused. 1. Remove CVE due to the use of old Druid dependencies 2. Improve compilation performance by removing Druid specific code & rules 3. Facilitate code maintenance by dropping unused code ### Does this PR introduce _any_ user-facing change? No really, in the sense that Druid integration is already broken in the past few releases. ### How was this patch tested? Existing tests -- This is an automated message from the Apache Git Service.
