Thank for your reply^^
but question is how we can write map reduce in C# without using Java
abstract classes and interfaces of Hadoop, should we only
write C# code according to map/reduce app logic?
what do you mean of app can run standalone? you mean its should be .exe
or .dll?
did you do map/reduce by C# & Hadoop before?
Oh, lot of question. sorry ...

I haven't used Mono but if your written program can run as a standalone and
read from stdin and write to stdout, then streaming is sufficient to run your
C# MR programs.

Dear All,

As you know for developing map/reduce app in hadoop we should extend and
implement special map and reduce abstract classes and interfaces,
and Hadoop pipes is for C++ not C#. The question is what we should do for C#?
*IS IT RIGHT THAT *
1- Just develop our C# code (maybe its better with MonoDevelop) according to
map/reduce abstract logic by developing map and reduce classes
2- Then introduce the map and reduce classes to the hadoop streaming.
Does hadoop streaming work with .ddl file?
Thanks for your help.
