             Summary: Query fails with char partition column
                 Key: HIVE-7889
                 URL: https://issues.apache.org/jira/browse/HIVE-7889
             Project: Hive
          Issue Type: Bug
          Components: Serializers/Deserializers
            Reporter: Mohit Sabharwal
            Assignee: Mohit Sabharwal


For a char partition column, JavaHiveCharObjectInspector attempts to cast HiveCharWritable to HiveChar:

{code}
create table partition_char_1 (key string, value char(20)) partitioned by (dt char(10), region int);

insert overwrite table partition_char_1 partition(dt='2000-01-01', region=1)
  select * from src tablesample (10 rows);

select * from partition_char_1 limit 1;

java.sql.SQLException: Error while compiling statement: FAILED: RuntimeException org.apache.hadoop.hive.ql.metadata.HiveException: Failed with exception org.apache.hadoop.hive.serde2.io.HiveCharWritable cannot be cast to org.apache.hadoop.hive.common.type.HiveCharjava.lang.ClassCastException: org.apache.hadoop.hive.serde2.io.HiveCharWritable cannot be cast to org.apache.hadoop.hive.common.type.HiveChar
