Duplicate MetricsName:getProtocolVersion

[Jon Lederman <jo...@me.com>]

Hi,

In the datanode logs I see an error about Duplicate MetricsName and Error register getProtocolVersion.  This may be related to an error in repiicatiion that I encountered earlier.
Does anyone have any thoughts?

tConnectors()[0].getLocalPort() returned 50070
