Connecting to HDP 2.0 with yarn client

    I downloaded and launched HDP 2.0 in VirtualBox and then tried to connect from java using YarnClient but came across the following error:

    1311 [IPC Client (1943692956) connection to /192.168.0.31:8050 from lordorient] DEBUG org.apache.hadoop.ipc.Client.run null – IPC Client (1943692956) connection to /192.168.0.31:8050 from lordorient: starting, having connections 1

    Connection reaches its target. Just looked up server logs and it seems to be auth issue:

    2013-08-11 12:17:34,018 INFO ipc.Server (Server.java:doRead(763)) – IPC Server listener on 8050: readAndProcess threw exception java.io.IOException: Unable to read authentication method from client 192.168.0.48. Count of bytes read: 0

    at org.apache.hadoop.ipc.Server$Listener$Reader.doRunLoop(Server.java:557)
    at org.apache.hadoop.ipc.Server$Listener$Reader.run(Server.java:532)

    But all the docs are deadly silent about how should I configure all this security stuff on client side. Is there anybody around to help me?

    Finally I made this work. Here is the description of what needs to be done: http://fusionworks.md/connecting-to-yarn-on-hortonworks-hdp-2-0/
