[BugFix] Fix stats are not correct in skew join rule for partitioned hive table
Why I'm doing:
at skew join rule, row count in statistics is not correct when hive table is partitioned table
What I'm doing:
- Get all partition statistics at skew join rule (beacuse this rule run before prune partition rule, do not known the selected partitions)
- If can not get basic statistics from internal statistics(statistics db), get table statistics from connector metadata Fixes #issue
