I have used [Docker Hub](https://hub.docker.com/r/julialang/hadoop/) site for installing and using hadoop. Everything got installed successfully. Using the jps command I could see the working nodes

```julia
root@c584ec74aae3:/# jps
986 NodeManager
791 ResourceManager
396 DataNode
602 SecondaryNameNode
1528 Jps
240 NameNode
root@c584ec74aae3:/#

```

Can someone say/post how to do map reduce in julia as explained in Michael knolls website.  
Thanx
