> 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.
