> After HBASE-13768 we check at startup in secure configurations if our znodes have the
correct ACLs. However when checking the ACL we compare the Kerberos fullname, which includes
the host component. We should only compare the shortname, the principal. Otherwise in a multimaster
configuration we will unnecessarily reset ACLs whenever any master running on a host other
than the one that initialized the ACLs makes the check. You can imagine this happening multiple
times in a rolling restart scenario.
