Ah yes, not having compatibility is a pain for sure :(
The only problem though is, on one hand we have compatibility to maintain,
and on the other, inconsistent behavior among different options of
dfsrouteradmin.
Any decision is fine though :)

> DFS router admin returns non-zero status code for unsuccessful attempt to add
> or update mount point. However, same is not the case with removal of mount
> point.
> For instance,
> {code:java}
> bin/hdfs dfsrouteradmin -add /data4 ns1 /data4
> ..
> ..
> Cannot add destination at ns1 /data4
> echo $?
> 255 {code}
> {code:java}
> /hadoop/bin/hdfs dfsrouteradmin -rm /data4
> ..
> ..
> Cannot remove mount point /data4
> echo $?
> 0{code}
> Removal of mount point should stay consistent with other options and return
> non-zero (unsuccessful) status code.
