Íñigo Goiri commented on HDFS-13068:
------------------------------------
Thanks [~linyiqun] for [^HDFS-13068.001.patch] .
Most of the patch is just the interface part so it's big but the changes are
pretty contained.
For the regular {{dfsadmin}} the way the option is there, is something like:
{{[-safemode enter | leave | get | wait | forceExit]}}, it should be something
like that.
We may want to add an option to get the state.
