Zhijie Shen commented on YARN-737:
----------------------------------

Search around the source code. It seems that the following exceptions can be 
unwrapped as well.

TestLocalContainerAllocator
{code}
        when(scheduler.allocate(isA(AllocateRequest.class)))
          .thenThrow(RPCUtil.getRemoteException(new IOException("forcefail")));
{code}

ContainerManagerImpl
{code}
    try {
      tokenIdentifier = BuilderUtils.newContainerTokenIdentifier(token);
    } catch (IOException e) {
      throw RPCUtil.getRemoteException(e);
    }
{code}

{code}
      } catch (IOException e) {
        throw RPCUtil.getRemoteException(e);
      }
{code}

MiniYARNCluster

{code}
              } catch (YarnException ioe) {
                LOG.info("Exception in heartbeat from node " + 
                    request.getNodeStatus().getNodeId(), ioe);
                throw RPCUtil.getRemoteException(ioe);
              }
{code}

{code}
              } catch (YarnException ioe) {
                LOG.info("Exception in node registration from "
                    + request.getNodeId().toString(), ioe);
                throw RPCUtil.getRemoteException(ioe);
              }
{code}
