- [HUDI-172] Cleanup Maven POM/Classpath - Fix ordering of dependencies in poms, to enable better resolution - Idea is to place more specific ones at the top - And place dependencies which use them below them - [HUDI-68] : Automate demo steps on docker setup - Move hive queries from hive cli to beeline - Standardize on taking query input from text command files - Deltastreamer ingest, also does hive sync in a single step - Spark Incremental Query materialized as a derived Hive table using datasource - Fix flakiness in HDFS spin up and output comparison - Code cleanup around streamlining and loc reduction - Also fixed pom to not shade some hive classs in spark, to enable hive sync
