From 3b0e761ba83cb063eb95734faece35378beebac4 Mon Sep 17 00:00:00 2001 From: Zhu Lingshan Date: Tue, 11 Jul 2017 09:26:55 -0500 Subject: dlm: print log message when cluster name is not set Print a message when a cluster name is not specified by the caller. In this case the cluster name configured for the dlm is used without any validation that it is the cluster expected by the application.
