Hi All,

I have a csv file ( separated by |) where data is like

id               data
                                       date
1            apple
                                  24-nov-2011
2            mango
                                26-nov-2011
3            <?xml version="1.0" encoding="utf-8"?>
                 <a>fruits</a>
                                28-nov-2011
4             papaya
                                 30-nov-2011
Since id=3 has new line in data field hive  takes only first
line and treats second line as different row.I want my full xml field
to be taken inside data in hive table .

it seems hive doesnt support            lines terminated by '|'

How to treat xml data in hive

Thanks & Regards
Prabhjot

Hive currently supports only new line as record separator. If you got
newline in in column values then you will need to preprocess your data and
remove new line from column values

How to preprocess data where millions of records are there out of
which only few thousands contain xml data

You can simply write a mapreduce job which will do the job for you
That will be readily available for hive table

You can use your custom mapreduce code. Just check the record type and if xml then preprocess to avoid new lines.
