Babulal updated CARBONDATA-2991:
Description:
During Query Execution sometime NegativeArraySizeException Exception in Some
Tasks . And sometime Executor is lost (JVM crash)

Issue Analysis :-
Possible Root Cause :- It is because existing memoryblock is removed while it
was in-use. This happened because duplicate taskid generated. Sometime freed
same memory addresses are assigned to another task which will initialize memory
block to0 and this cause NegativeSizeArrayException whereas sometime freed
memory will not be used any task of executor process but running task will try
to access it and as that address is not part of process so JVM crash will
happen.
*Steps to find cause*
*Add the code to create tasklist ids and add taskid to list on
setCarbonTaskInfo() , and if it is duplicate then Log a Warn message.*
Please check attachment.
Run the Query multiple time and found warn message in executor logs
