> When we are running `ANALYZE TABLE ... COMPUTE STATISTICS` or `ANALYZE TABLE ... COMPUTE STATISTICS FOR COLUMNS` all the basic statistics are collected by the BasicStatsTask class. This class tries to estimate the statistics by scanning the directory of the table. 
> In the case of non-native tables (iceberg, hbase), the table directory might contain metadata files as well, which would be counted by the BasicStatsTask when calculating basic stats. 
> Instead of having this logic, the HiveStorageHandler implementation should provide basic statistics.
