      Description

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

      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
