-----------------------------------------

Hello everybody.
I have tried to setup Hadoop and Hama cluster on my machine in pseudo-distr=
ibuted mode. I have set up Hadoop cluster and launched WordCount example su=
ccessfully. After that I tried to setup Hama in pseudo-distributed mode. Wh=
en I launched start-bspd.sh output was like in tutorial, but jps command di=
dn't show BspMasterRunner. I explored logs and found next line: "java.io.IO=
Exception: Broken pipe". Could someone help me to figure this issue out? I =
used tutorials from here[1] and here[2]. I also attached archive with logs =
of hama and main configuration files.
