Thanks [~linyiqun], for the review comments. Patch v2 addresses the same.
Please have a look.
KSM Version file is actually located inside the path "ozone_metadir_dir/ksm/"
The function to read
the ozone.metadata.dir config path is getScmMetaDir() which is misleading i
guess. KSM doesn't store the version file inside SCM MetaData Directory.

> KSM --createObjectStore command reads the ozone configuration information and
> creates the KSM version file and reads the SCM version file from the SCM
> specified.

> The SCM version file is stored in the KSM metadata directory and before
> communicating with an SCM KSM verifies that it is communicating with an SCM
> where the relationship has been established via createObjectStore command.
