Sachin Ramachandra Setty created CARBONDATA-3852:
----------------------------------------------------
Summary: CCD Merge with Partition Table is giving different
results in different spark deploy modes
Key: CARBONDATA-3852
URL: https://issues.apache.org/jira/browse/CARBONDATA-3852
Project: CarbonData
Issue Type: Bug
Components: spark-integration
Affects Versions: 2.0.0
Reporter: Sachin Ramachandra Setty
The result sets are different when run the sql queries in spark-shell --master
local and spark-shell --master yarn (Two Different Spark Deploy Modes)
