[HOTFIX] Avoid cleaning segments after reading tablestatus failed Why is this PR needed? 1. After reading tablestatus file failed, method TableProcessingOperations. deletePartialLoadDataIfExist will delete all related segments. 2. If the tablestatus file was removed, the system will delete all original segment before loading. What changes were proposed in this PR? 1. check the result of reading tablestatus file, if it is empty, no need to process. 2. if the table status was removed, the system shouldn't delete any segment. 3. re-factory code to avoid invoking getAbsolutePath method too many times. This closes #3899
