-Streaming issue ( URGENT )
Siddharth Tiwari 2012-08-20, 16:33
I have a python script which normally runs like this locally,
Python mapper.py file1 file2 2 .
How can I achieve this by using streaming API, and using the script as mapper. It actually joins the three files on a column which is passed as parameter ( numeric ) .
Also how can I use paste command in mapper to concatenate three files.
Ex, paste file1 file2 file3 > file4
This is in normal shell,
How to achieve it over streaming.
if possible please explain how can I achive it using multiple mappers and one reducer. It would be great If I could get some examples, tried searching a lot :(
Thanks in advance please help
Have a refreshing day !!!
