https://github.com/apache/carbondata/pull/2773 [CARBONDATA-2978] Fixed JVM crash issue when insert into carbon table from other carbon table
Problem:
When data is inserted from one carbon to other carbon table and unsafe load and query is enabled then JVM crash is happening.
Reason: When insert happens from one carbon table another table it uses same task and thread so it gets the same taskid and at the unsafe manager tries to release all memory acquired by the task even though load happens on the task.
Solution:
Check the listeners and ignore cache clearing.
