Resolving the problem

This defect will not impact the main usage of Flume, which is to transfer data. You can also get node configuration from Flume master console. Because the Flume latest version (1.2.0) architecture has changed, there is no Flume master any more. This issue does not exist in Flume NG. This is a fixed upstream issue.
