--------------------------------------
Could you explain more about the issue. What makes the partitions erroneous?
Did you try "Alter Table Touch" in the hive ddl?
> Alter table refresh command for external tables

> If the data at the location for a partitioned/non-partitioned external tables
> gets changed, the queries on the partition gives incorrect results.
> The workaround is to remove all the erroneous partitions and then add them
> again and then it works perfectly fine.
> We should have a refresh command to do the same per partition or for all the
> partitions in an external table.
