> In HDFS-14818, we proposed a patch to support checking native pmdk lib. The
> expected target is to display hint to user regarding pmdk lib loaded state.
> Recently, it was found that pmdk lib was not successfully loaded actually but
> the `hadoop checknative` command still tells user that it was. This issue can
> be reproduced by moving libpmem.so* from specified installed path to other
> place, or directly deleting these libs, after the project is built.
