> Map join task may cause OOM due to orc compression , in most cases , a backup
> task will be invoked. However , if the size of hash table is close to memory
> limit, the task which load the hash table will NOT fail . OOM will happen in
> next task witch do local join. The load task has a backup but next task not.
> So in this case , the whole query will fail.
