在猪中读取 csv,csv 文件包含带引号的逗号
问题描述:
所以我的数据看起来像这样
So my data looks something like this
asdf, asdf, "adsf,qwef", asdf
当我使用 Pig 读取数据时
When i read that data in pig using
PigStorage(',')
它将adsf,qwef"存储为两个数据,并像这样存储
It stores the "adsf,qwef" as a two data, and stores it like
{ "adsf } { qwef" }
我希望将引号视为单个数据.
I want quotes to be treated as single data.
我该怎么办?
我正在尝试编写一个pigscript来做到这一点.
答
您应该使用 CSVLoader:
You should use the CSVLoader:
data = LOAD 'my.csv' USING org.apache.pig.piggybank.storage.CSVExcelStorage()
AS (...);
其中 ... 是标识符.
Where the ... is the identifiers.
