All host lookups are modified by the hosts entry in /etc/nsswitch.conf.
This should generally be files dns (or files {stuff} dns {stuff}).
First you need to check that.
Next you need to consider what's actually happening here.
1. Dig is explicitly looking for the name maroon..
2. Ping, on the other hand, is using the resolver library that honours
the search directive in /etc/resolv.conf. This means that the value will
be appended to each unqualified request prior to lookup, i.e. ping will
expect to find maroon.local.
My recommendation would be either to change your local DNS server so that
it adds .local to all unqualified hostnames, or to remove the search
directive from your resolv.conf.
I think your next posting mentions that you're using dnsmasq, in which
case the options to consider would be domain and expand-hosts, and
possibly domain-needed. See the example dnsmasq configuration file
at /usr/share/doc/dnsmasq-base/examples/dnsmasq.conf.example.
