> Given that 0.13 is incredibly old at this point, I think the likelihood of anyone trying
to start an 0.20+ namenode on an 0.13 directly layout is essentially nil. The intentionally-corrupt
"${dfs.name.dir}/image/" directory just serves to confuse new users at this point, so I propose
removing it.
> If no one objects, I'll submit a patch. If there are objections, I propose at least adding
a README explaining its purpose (same text as in the corrupt fsimage file)
