[Hadoop-RDMA-discuss] Fail to kick off hdfs when use IB driver provided by system

[Xiaoyi Lu]

Hi, Yongxin,

Thanks for your interest in our project.

>From the error you got, it seems that Hadoop can not open your IB device properly. This seems like a system issue. Are you able to run some basic IB level micro-benchmarks on your nodes? Please let us know.

Thanks,
Xiaoyi
