------------------------------------
I assume it should only prevent the regionserver/master daemons from starting?
> Add sanity check for system configs in hbase-daemon wrapper

> Key: HBASE-2750
> URL: https://issues.apache.org/jira/browse/HBASE-2750
> Project: HBase
> Issue Type: New Feature
> Components: scripts
> Affects Versions: 0.90.0
> Reporter: Todd Lipcon
> Priority: Minor
> Labels: noob
>
> We should add a config variable like MIN_ULIMIT_TO_START in hbase-env.sh. If
> the daemon script finds ulimit < this value, it will print a warning and
> refuse to start. We can make the default set to 0 so that this doesn't affect
> non-production clusters, but in the tuning guide recommend that people change
> it to the expected ulimit.
> (I've seen it happen all the time where people configure ulimit on some
> nodes, add a new node to the cluster, and forgot to re-tune it on the new
> one, and then that new one borks the whole cluster when it joins)
