> Support custom partition patterns in MSCK repair table
> ------------------------------------------------------
>
> Key: HIVE-28676
> URL: https://issues.apache.org/jira/browse/HIVE-28676
> Project: Hive
> Issue Type: New Feature
> Reporter: Venkatasubrahmanian Narayanan
> Assignee: Venkatasubrahmanian Narayanan
> Priority: Minor
> Labels: pull-request-available
>
> MSCK repair table doesn't support custom partition patterns. While it is not
> possible to cover the most general case due to ambiguities in resolving
> partition keys, we can extend the feature to cover the simpler cases.
>
> An example of a case that is impossible to resolve, to be clear:
>
> A Hive table with 2 partition keys k1 and k2, with a custom partition format
> of ${k1}-${k2} . If we have a path "x-y-z", it is impossible in general to
> know if this corresponds to the partition k1='x-y',k2='z' or k2='x',k2='y-z'
> . But such cases should hopefully be rare in practice.
