> After [PR1984|https://github.com/apache/carbondata/pull/1984] merged, it doesn't delete the lock files when unlock, there are many useless lock files in table path, especially segment lock files, they grow after every batch loading.
> Solution :
> 1. add a child path into table path, called Locks, all lock files will be stored in this path;
> 2. Before loading, get all useless segment lock files and delete them, because just segment lock files will grow, other lock files dosen't grow.
