---------------------------------------
Summary: MSCK REPAIR cannot discover partitions with upper case
directory names.
Key: HIVE-23347
URL: https://issues.apache.org/jira/browse/HIVE-23347
Project: Hive
Issue Type: Bug
Components: HiveServer2
Affects Versions: 3.1.0
Reporter: Sankar Hariappan
Assignee: Adesh Kumar Rao
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
