[CARBONDATA-3874] segment mismatch between maintable and SI table when load with concurrency Why is this PR needed? 1. segment mismatch between main table and SI table with concurrency loads 2. In concurrent loads, if one of the load failed for SI table then 'isSITableEnabled' will be disabled(isSITableEnabled = false). So in failed SI event listener case we are just checking SI enabled is true(isSITableEnabled == true) then we are not loading current load to SI table. In concurrent scenarios, this might be happening as SI enabled state is true but segment difference may exist. What changes were proposed in this PR? So instead of checking just SI enabled is true(isSITableEnabled == true) we should also check if any segment difference between main table and SI table. The final output flag checking will be as follows. if ( isSITableEnabled == true || mainTblAndSidiff == true ) { --- } This closes #3811
