Ok
I have created a one liner csv file as follows:
cat testme.csv
360,10/02/2014,"?2,500.00",?0.00,"?2,500.00"
I use the following in Spark to split it
csv=sc.textFile("/data/incoming/testme.csv")
csv.map(_.split(",")).first
res159: Array[String] = Array(360, 10/02/2014, "?2, 500.00", ?0.00, "?2,
500.00")
That comes back with an array
Now all I want is to get rid of “?” and “,” in above. The problem is I have a
currency field “?2,500.00” that has got an additional “,” as well that messes
up things
replaceAll() does not work
Any other alternatives?
Thanks,

Subject: Re: Hive REGEXP_REPLACE use or equivalent in Spark
Use the scala method .split(",") to split the string into a collection of
strings, and try using .replaceAll() on the field with the "?" to remove it.

Hi,
What is the equivalent of this Hive statement in Spark
select "?2,500.00", REGEXP_REPLACE("?2,500.00",'[^\\d\\.]','');
+------------+----------+--+
| _c0 | _c1 |
+------------+----------+--+
| ?2,500.00 | 2500.00 |
+------------+----------+--+
Basically I want to get rid of "?" and "," in the csv file
The full csv line is
scala> csv2.first
res94: String = 360,10/02/2014,"?2,500.00",?0.00,"?2,500.00"
I want to transform that string into 5 columns and use "," as the split
