Review comment:
I am not familiar with the old issue, but now our classpath is separated
from yarn. We can use any newer rocksdb (but we should use the same versions
for all the hdds/ozone projects)
I think it's safe to use any new rocksdb feature if you think metrics should
be turned on by default...
