If we use the second approach, can user query this table from hive side?
Let's assume that the user can use msck command to recover partitions
(https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-RecoverPartitions(MSCKREPAIRTABLE)).
My main question is that if we preserve the partition column names' case
sensitivity in fs paths, will hive be able to read the data? Or Hive will use
all lower-case paths and then fails to read those partitions?
