Counter Initialization causes NPE

```Java
CREATE EXTERNAL TABLE api_hit_parquet_test ROW FORMAT SERDE 'com.foursquare.hadoop.hive.serde.RecordV2SerDe' WITH SERDEPROPERTIES ('serialization.class' = 'com.foursquare.logs.gen.ApiHit') STORED AS INPUTFORMAT 'com.foursquare.hadoop.hive.io.HiveThriftParquetInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat' LOCATION '/user/bly/api_hit_parquet' TBLPROPERTIES ('thrift.parquetfile.input.format.thrift.class' = 'com.foursquare.logs.gen.ApiHit’)
```

The table is successfully created, and I can verify the schema is correct by running DESCRIBE FORMATTED on it. However, when I try to do a simple SELECT \* on the table, I get the following stack trace:

```Java

I have spent some time following this stack trace, and it appears that the error lies in the Counter code, which is odd because I don’t do anything with that. Is there some way I need to initialize counters?

To be specific, I have found that MapReduceCounterAdapter is being created with a null parameter. Here is the constructor:

```Java
public MapReduceCounterAdapter(Counter adaptee) {
this.adaptee = adaptee;
}
```

So adaptee is being passed as null, and then getting called later on, causing my NullPointerException.

The adaptee parameter is created by this method:

```Java
public static Counter getCounter(TaskInputOutputContext context,
String groupName, String counterName) {
return (Counter) invoke(GET_COUNTER_METHOD, context, groupName, counterName);
}
```

Bắt đầu với MapReduceCounterAdapter và ContextUtil.getCounter, sau đó lần theo lời gọi từ HiveThriftParquetInputFormat.scala:46-47 qua ParquetFileReader.readNextRowGroup. Tái hiện lỗi SELECT và xác minh rằng việc đọc bản ghi đầu tiên không còn gây ra NullPointerException đã báo cáo khi sử dụng bộ đếm.
