UnsupportedOperationException: Currently the writer can only accept BytesRefArrayWritable

往Hive表中插入时报错：

貌似建表是格式的问题：http://comments.gmane.org/gmane.comp.java.hadoop.hive.user/2849

建表语句如下：

CREATE  TABLE client_user_type_installtime(
  userkey string,
  mos string,
  type string)
PARTITIONED BY ( 
  dt string,
  installtime_type string)
ROW FORMAT DELIMITED 
  FIELDS TERMINATED BY '9' 
  LINES TERMINATED BY '10' 
STORED AS INPUTFORMAT 
  'org.apache.hadoop.hive.ql.io.RCFileInputFormat' 
OUTPUTFORMAT 
  'org.apache.hadoop.hive.ql.io.RCFileOutputFormat'

修改建表语句：

CREATE  TABLE client_user_type_installtime(
  userkey string, 
  mos string, 
  type string)
PARTITIONED BY ( 
  dt string, 
  installtime_type string)
ROW FORMAT SERDE 
  'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe' 
STORED AS INPUTFORMAT 
  'org.apache.hadoop.mapred.TextInputFormat' 
OUTPUTFORMAT 
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'

重建后插入成功。
