> Unable to read complete data of an external hive table stored as ORC & pointing to a managed table's data files that is getting stored in sub-directories.
> The count also does not match unless the path is given with a *.
> *Example This works:-*
> "adl://<adls_name>.azuredatalakestore.net/clusters/<cluster path>/hive/warehouse/db2.db/tbl1/***"
> But the above creates a blank directory named *** in ADLS(Azure Data Lake Store)
>
> The below one does not work when a SELECT COUNT ( * ) is executed on this external file. It gives partial count.
> CREATE EXTERNAL TABLE IF NOT EXISTS db1.tbl1 (
> Col_1 string,
> Col_2 string
> STORED AS ORC
> LOCATION "adl://<adls_name>.azuredatalakestore.net/clusters/<cluster path>/hive/warehouse/db2.db/tbl1/"
> )
