Thank Sergey and Matthew,

Matt, i follow the this instructions. Details step by step installation,
configuration anh create cluster at:
https://docs.google.com/document/d/1r1aYEQ-fugY8h3vbG5Wvk0FfVRUk_oDmaRDtpUiyK-0/edit

When ssh to instance-master run: sudo su hadoop; cd ~; hadoop jar
/usr/share/hadoop/hadoop-examples-1.2.1.jar pi 10 100
Seems it worked. But it's still error:

    Caused by: java.lang.OutOfMemoryError: Java heap space

        ...

)


First, i set flavor for a node group template is 1GB Ram and 10GB Disk.
Then i set 2GB Ram and 20GB Disk. But still this error.
Note:
 - The current, i'm setting disable Swift and MySQL.
 - I set default HDFS, MapReduce,....

I see:
 - Service hadoop-* (hadoop-namenode) still "not running"
 - Show UI Sahara: HDFS, MapReduce: No Configuratiions (
