@liuml07 We have checked for several times, the failure tests are not
related with this patch, and I found almost all of the HDFS-* patches are not
pass the hadoop-hdfs unit tests, like
https://github.com/apache/hadoop/pull/2275
https://github.com/apache/hadoop/pull/2205
So maybe the failure tests are not blocker?

> The non-volatile memory NVDIMM is faster than SSD, it can be used
> simultaneously with RAM, DISK, SSD. The data of HDFS stored directly on
> NVDIMM can not only improves the response rate of HDFS, but also ensure the
> reliability of the data.
