-----------------------------------------
Summary: Carbon1.3.0-Pre-AggregateTable - Pre-aggregate tables
creation in Spark-shell sessions are not used in the beeline session
Key: CARBONDATA-1777
URL: https://issues.apache.org/jira/browse/CARBONDATA-1777
Project: CarbonData
Issue Type: Bug
Components: data-load
Affects Versions: 1.3.0
Environment: Test - 3 node ant cluster
Reporter: Ramakrishna S
Assignee: Kunal Kapoor
Fix For: 1.3.0
Steps:
1. Create table and load with data
2. Run update query on the table - this will take table metalock
3. In parallel run the pre-aggregate table create step - this will not be
allowed due to table lock
4. Rerun pre-aggegate table create step
*+Expected:+* Pre-aggregate table should be created
*+Actual:+* Pre-aggregate table creation fails
