java - How to read file in the same project when I do MapReduce -

i need use mapreduce read contents orc files, @ same time, hope when program launched, can automatically load 1 file locates in same jar package of mapreduce program.

my tree folders listed below:

mrproj/ ├── bin │   ├── com │   │   ├── folder ├── **file_i_want_to_readin.dat** ├── lib │   ├── jar01 │   ├── jar02 │   ├── .... └── src     ├── com     │   ├── **my_mapreduce_folder**             ├── **mr.java** 

there no problem me read orc files on hdfs, seems when running mapreduce, program can not locate file: "file_i_want_to_readin.dat".

the codes read file listed below:

public static hashmap<string, string> readbinaryfile(string inputdir) {      hashmap<string, string> opt = new hashmap<string, string>();     string k = "";     try {         datainputstream dis = new datainputstream(new bufferedinputstream(new fileinputstream(new file(inputdir))));         while (dis.available() > 0) {             k = dis.readutf();             ... other codes ...         }         dis.close();     } catch (filenotfoundexception e) {         e.printstacktrace();     } catch (ioexception e) {         // todo auto-generated catch block         e.printstacktrace();     }     return opt; }
