>          Issue Type: Bug
>          Components: Hive
>    Affects Versions: 4.0.0
>            Reporter: László Pintér

> 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.
