rdma for hawq

I found that https://github.com/Mellanox/r4h support hdfs use RDMA, but still need client app use it. 

But i do not found how to use RDMA for hawq? 

Is it a feature now? 

How can i use it? 

Best wishes

Thanks very much. 

BTW, do not need to set hawq host ip as IB ip?

Currently, HAWQ does not support RDMA. If you do want to use and use infiniband, you can use IPoIB. Then you can use hawq as usual. 

Thanks
