You can't have an order where u start oozie and then HDFS.
It may not be acceptable to all users ( mainly ops).

I am ok with adding a config that controls fail fast. But the default config
should work for most newbie oozie users. Overriding configs are for advanced
oozie users.
With current oozie code, if there is any usecase where the workflow will fail
without sharelib, we should set the default config value as true(so that it
fails fast, instead of wasting hours later to figure out which jar has the
missing class and why that jar is not loaded. Trust me, we have spent enough
time debugging these). If current oozie will work always even without sharelib,
you can set it to false. I haven't gone through the recent sharelib changes, so
I don't know how exactly its used. Its your call. Make sure the default
installation works for new oozie users
Between, if hdfs is down when oozie comes up, what will happen to the workflows
that are launched? Ops will re-run the killed workflows? Isn't it too much
effort?

> "OOZIE-1584 Setup sharelib using script and pickup latest(honor
> ship.launcher) and remove DFS dependency at startup" has removed sharelib
> dependency at startup.
> If DFS is down or sharelib is misconfigured. Server will start without
> loading sharelib, admin can issue sharelibupdate command to load sharelib.
> This is good, may not be acceptable in production. If sharelib is
> misconfigured then oozie server will come up without loading sharelib and all
> submitted hadoop job will fail.
> Better to have a property to shutdown oozie server, if sharelib
> initialization fails.
