    DRILL-3746: Get Hive partition values from MetaStore instead of from …

    …parsing the partition location path
    
    1) Added a partition with custom location to test Hive table. Existing 
partition tests now work after the fix.
    2) Enabled a test which was disabled previously due to a bug in interpreter 
code

> Hive query fails if the table contains external partitions

>            Reporter: Venki Korukanti
>
> If Hive contains a table which has external partitions, Drill fails in 
> partition pruning code, which causes the query to fail.
> {code}
> CREATE TABLE external_partition_test (boolean_field BOOLEAN) PARTITIONED BY 
> (boolean_part BOOLEAN);
> ALTER TABLE external_partition_test ADD PARTITION (boolean_part='true') 
> LOCATION '/some/path';
> ALTER TABLE external_partition_test ADD PARTITION (boolean_part='false') 
> LOCATION '/some/path';
> {code}
> Query:
> {code}
> SELECT * FROM hive.`default`.external_partition_test where boolean_part = 
> false
> {code}
> Exception:
> {code}
> java.lang.StringIndexOutOfBoundsException
> String index out of range: -14
> at java.lang.String.substring(String.java:1875) ~[na:1.7.0_45]

> {code}
> Looking at {{HivePartitionLocation}}, it looks like we are depending on the 
> organization of files on FileSystem to get the partition values. We should 
> get the partition values from MetaStore.
