Hi,
I have written a ‘Pig Script’ which is processing Sequence files given as
input.
It is working fine but there is one problem mentioned below.
I have repetitive statements in my pig script, as shown below:
- Filtered_Data _1= FILTER BagName BY ($0 matches 'RegEx-1');
-
Load the regex patterns from a file (one pattern per line), CROSS their
relation with BagName, and then use SelectFieldByName UDF to summon the
regex pattern from the regex relation.

I believe you can use a field name against
Are these regex static? If yes, this is easily achieved with embedding your
script in Java or any other language that Pig supports
http://pig.apache.org/docs/r0.13.0/cont.html
You could also possibly write a UDF that loops through all the regex and
returns result.

Hi Ankur,
Is the list of regular expressions static or dynamic? If it's a static
list, you can collapse all the filter operators into a single operator and
use the AND keyword to combine them.
E.g.
Filtered_Data = FILTER BagName BY ($0 matches 'RegEx-1') AND ($0 matches
'RegEx-2') AND ($0
Actually, I don't think you need SelectFieldByValue. Just use the name of
the field directly.

In case you haven't seen this already, take a look at

optimizing your pig scripts.

Thanks for replying everyone. Few comments to everyone's suggestion.
1 I am processing sequence file which consist of many CSV files. I need
to extract only few among all CSV'S. So that is the reason I am doing
'SelectFieldByValue'
which is file name in my case not by field directly.
2 All
It looks like the best option at this point is to write a custom UDF that
takes loads a set of regular expressions from file and runs the data
through all of them.

If you can describe the layout of your input files more thoroughly, it
would help.

Hi Pradeep
You are right. Updated the right answers in the blog.
This may help anyone thinking about investing in that particular test
package.
