我尝试从保存到 HDFS 的 CSV 文件创建表。问题是 csv在引号内包含换行符。CSV 中的记录示例：

ID,PR_ID,SUMMARY
2063,1184,"This is problem field because consists line break

This is not new record but it is part of text of third column
"

我创建了蜂巢表：

CREATE TEMPORARY EXTERNAL TABLE  hive_database.hive_table
(   
    ID STRING,
    PR_ID STRING,
    SUMMARY STRING 
)
row format serde 'com.bizo.hive.serde.csv.CSVSerde'
with serdeproperties (
    "separatorChar" = ",",
    "quoteChar"     = "\"",
    "escapeChar"  = "\""
)     
stored as textfile
LOCATION '/path/to/hdfs/dir/csv'
tblproperties('skip.header.line.count'='1');

然后我尝试计算行数（正确的结果应该是 1）

Select count(*) from hive_database.hive_table;

但结果是 4 what 是不正确的。你知道如何解决它吗？谢谢大家。
