xuchuanyin updated CARBONDATA-2246:
-----------------------------------
Description:
Currently in carbon data loading, if we enable the unsafe loading and specify corresponding properties, data loading will end in OOM.
The key properties to reproduce the bug are as following:
```
01: CarbonProperties.getInstance().addProperty(CarbonCommonConstants.ENABLE_INMEMORY_MERGE_SORT, "true") CarbonProperties.getInstance().addProperty(CarbonCommonConstants.ENABLE_UNSAFE_SORT, "true")
02:
03: // unsafe sort memory manager
04: CarbonProperties.getInstance().addProperty(CarbonCommonConstants.IN_MEMORY_STORAGE_FOR_SORTED_DATA_IN_MB, "1024")
05:
06: // unsafe working memory manager
07: CarbonProperties.getInstance().addProperty(CarbonCommonConstants.UNSAFE_WORKING_MEMORY_IN_MB, "512")
08:
09: // one unsafe page, better if loading_cores * this < memory
10: CarbonProperties.getInstance().addProperty(CarbonCommonConstants.OFFHEAP_SORT_CHUNK_SIZE_IN_MB, "512")
```
