> For the following scenario, we expect MSCK REPAIR to discover partitions but it couldn't.
> 1. Have partitioned data path as follows.
> hdfs://mycluster/datapath/t1/Year=2020/Month=03/Day=10
> hdfs://mycluster/datapath/t1/Year=2020/Month=03/Day=11
> 2. create external table t1 (key int, value string) partitioned by (Year int, Month int,
Day int) stored as orc location hdfs://mycluster/datapath/t1'';
> 3. msck repair table t1;
> 4. show partitions t1; --> Returns zero partitions
> 5. select * from t1; --> Returns empty data.
> When the partition directory names are changed to lower case, this works fine.
> hdfs://mycluster/datapath/t1/year=2020/month=03/day=10
> hdfs://mycluster/datapath/t1/year=2020/month=03/day=11
