When i query data from a lzo table ， I found in results ： the length of the
current row is always largr than the previous row， and sometimes，the current
row contains the contents of the previous row。 For example ，i execute a sql
,"select * from web_searchhub where logdate=2015061003", the result of sql
see blow.Notice that ,the second row content contains the first row content.

I think this error is caused by the Text reuse,and I found the solutions .
Addicational, table create sql is :
CREATE EXTERNAL TABLE `web_searchhub`(
`line` string)
PARTITIONED BY (
`logdate` string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\\U0000'
WITH SERDEPROPERTIES (
'serialization.encoding'='GBK')
STORED AS INPUTFORMAT "com.hadoop.mapred.DeprecatedLzoTextInputFormat"
OUTPUTFORMAT
"org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat";
LOCATION
