Commit Message

[CARBONDATA-3123] Fixed JVM crash issue with CarbonRecordReader(SDK Reader).

Problem:
As CarbonReaderBuilder is executed on the main thread therefore while Reader creation we are setting TaskId to threadlocal. When multiple readers are created using the split API then the TaskID for the last initialized reader would be overridden and all the readers will use the same TaskID.
Due to this when one reader is reading and the other reader is freeing memory after its task completion the same memory block would be cleared and read at the same time causing SIGSEGV error.

Solution:
Do not set TaskID to thread local while Reader Initialization. ThreadLocalTaskInfo.getCarbonTaskInfo will take care of assigning new TaskID if not already present.

This closes #2945
