Thanks. replacing localhost by IP address in tracer file removed the error.

Hi Ranjan,

Looks like that tablet server is trying to send traces (metrics/timings) 
to the tracer (Accumulo trace server which writes them to an Accumulo 
table).

Can you verify that the tracer is actually running on your system? See 
$ACCUMULO_CONF_DIR/tracers for the hosts that they are running on. Also, 
make sure you provided a reachable address if you're running on more 
than one node (e.g. not localhost).
