> ----------------------------------------------------------
>
> Key: DRILL-3746
> URL: https://issues.apache.org/jira/browse/DRILL-3746
> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Reporter: Venki Korukanti
> Assignee: Venki Korukanti
> Fix For: 1.2.0

>
> 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.
