[jira] [Created] (SPARK-10793) Make sparks use/subclassing of hive
more maintainable
Steve Loughran created SPARK-10793:
--------------------------------------
Summary: Make sparks use/subclassing of hive more maintainable
Key: SPARK-10793
URL: https://issues.apache.org/jira/browse/SPARK-10793
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 1.5.0
Reporter: Steve Loughran
The latest spark/hive integration round has closed the gap with Hive versions, but the integration is still pretty complex
# SparkSQL has deep hooks into the parser
# hivethriftserver uses "aggressive reflection" to inject spark classes into the Hive base classes.
# there's a separate org.sparkproject.hive JAR to isolate Kryo versions while avoiding the hive uberjar with all its dependencies getting into the spark uberjar.
We can improve this with some assistance from the other projects, even though no guarantees of stability of things like the parser and thrift server APIs are likely in the near future
