> It is quite common that there is the discrepancy between partition directory
> and its HMS metadata, simply because the directory could be added/deleted
> externally using hdfs shell command. Technically it should be fixed by MSCK
> and alter table .. add/drop command etc, but sometimes it might not be
> practical especially in a multi-tenant env. This discrepancy does not cause
> any problem to Hive, Hive returns no rows for a partition with an invalid
> (e.g. non-existing) path, but it fails the Pig load with HCatLoader, because
> the HCatBaseInputFormat getSplits throws an error when getting a split for a
> non-existing path. The error message might looks like:
> {code}
> Caused by: org.apache.hadoop.mapred.InvalidInputException: Input path does
> not exist:
> hdfs://xyz.com:8020/user/hive/warehouse/xyz/date=2016-01-01/country=BR
